Synthesis and Radical Copolymerization of Novel Phenyl-Disubstituted Propyl Cyanoacrylates- Juniper Publishers

JUNIPER PUBLISHERS- ACADEMIC JOURNAL OF POLYMER SCIENCE

Abstract

Novel phenyl-disubstituted propyl 3-(R-phenyl)-2-cyanoacrylates, RPhCH=C(CN)CO2C3H7 (where R is 2-fluoro-5-methyl, 3-iodo-4-methoxy, 5-iodo-2-methoxy, 3,5-dichloro, 3,4-difluoro, 3,5-difluoro, 2-chloro-4-fluoro, 2-chloro-6-fluoro, 3-chloro-2-fluoro, and 3-chloro-4-fluoro) were prepared using condensation of substituted benzoic aldehydes and propyl ester of cyanoacetic acid. The ethynyl benzene copolymerization of novel cyanoacrylates was conducted in solution with radical initiation at 70 C. Nitrogen analysis, 1H & 13C NMR was used to analyze composition and the structure. Thermal behavior of the copolymers was analyzed by DSC and TGA.

Keywords: Radical copolymerization; Styrene copolymers; Trisubstituted ethylene’s; Cyanoacrylates

Introduction

Ring–functionalized trisubstituted ethylene’s (TSE), esters of 3-phenyl-2-cyanoacrylates, R1PhCH=C(CN) CO2R2 continue to attract attention as compounds with interesting properties and as comonomers for modification of commercial polymers. 3,4-Difluorophenyl substituted methyl 3-phenyl-2-cyanoacrylate was used in synthesis and studies of histamine H2 agonistic activity [1]. Ethyl 3-phenyl-2-cyanoacrylate was used in studies of stereoselective cascade assembling of (1R*,2S*)-1-cyano-5,7-dialkyl-4,6,8-trioxo-2-aryl-5,7-diazaspiro[2.5]octane-1-carboxylates [2] and analgesic activity of 6-fluoroindan-1-carboxylic acid [3]. Alkyl 2-cyanoacrylates are a family of vinyl monomers renowned for their high reactivity, instant adhesive properties, and wide-ranging applications [4].

We have reported synthesis and ethynylbenzene copolymerization of similar ring-substituted methyl [5], ethyl [6], & butyl 3-phenyl-2-cyanoacrylates [7]. With the objective to design novel structures, that could serve as a spring board for further development of novel materials with new properties and applications, we have prepared halogen ring-disubstituted propyl 3-phenyl-2-cyanoacrylate (PPCA), RPhCH=C(CN)CO2C3H7sub>, where R is 2-fluoro-5-methyl, 3-iodo-4-methoxy, 5-iodo-2-methoxy, 3,5-dichloro, 3,4-difluoro, 3,5-difluoro, 2-chloro-4-fluoro, 2-chloro-6-fluoro, 3-chloro-2-fluoro, and 3-chloro-4-fluoro, and copolymerize them with ethynylbenzene. To the best of our knowledge, there have been no reports on either synthesis of these propyl phenyl cyanoacrylates, nor their copolymerization with ethynylbenzene.

Experimental

All benzoic aldehydes, propyl cyanoacetate, piperidine, ethynylbenzene, 1,1’-azobiscyclohexanecarbonitrile, (ABCN), and toluene supplied from Sigma-Aldrich Co., were used as received. The melting points and Tg, were measured with TA Model Q10 DSC. The thermal stability of the copolymers was measured by TGA TA Model Q50 from ambient temperature to 800 ºC at 20 ºC/min. The MW of the copolymers was determined by GPC using an Altech 426 HPLC pump at an elution rate of 1.0mL/min; Phenogel 5μ Linear column at 25 ºC and Viscotek 302 detector. 1H & 13C NMR spectra were obtained on 10–25% (w/v) monomer or polymer solutions in CDCl3sub> at ambient temperature using Avance 300MHz spectrometer. Elemental analyses were performed by Midwest Microlab, LLC (IN).

Results and Discussion

PPCA synthesis

The ring-substituted propyl 3-phenyl-2-cyanoacrylates (PPCA) were synthesized by Knoevenagel condensation [8] of a ring-substituted benzoic aldehyde with propyl cyanoacetate, catalyzed by base, piperidine (1).

Where R is 2-fluoro-5-methyl, 3-iodo-4-methoxy, 5-iodo- 2-methoxy, 3,5-dichloro, 3,4-difluoro, 3,5-difluoro, 2-chloro- 4-fluoro, 2-chloro-6-fluoro, 3-chloro-2-fluoro, & 3-chloro-4- fluoro. The preparation procedure was essentially the same for all the monomers. In a typical synthesis, equimolar amounts of propyl cyanoacetate and an appropriate ring-substituted benzoic aldehyde were mixed in equimolar ratio in a 20mL vial. A few drops of piperidine were added with stirring. The product of the reaction was isolated by filtration and purified by crystallization from 2-propanol. The condensation reaction proceeded smoothly, yielding products, which were purified by conventional techniques.

Copolymerization

The PPCA monomers when mixed with ethynylbenzene, EB at EB/PPCA = 3 (mol) formed copolymers as indicated by white flaky precipitates in high excess of methyl alcohol. The conversion of the EB-PPCA copolymers was maintained 10–20% to decrease compositional drift (Table 1). The PPCA content 8.4- 25.8 mol% in the copolymers indicated relatively high reactivity of the PPCA monomers towards EB radical Figure 1.

The EB-PPCA copolymers were soluble in tetrahydrofuran, ethyl acetate, chloroform and dimethylformamide, and insoluble in methyl alcohol, ethyl and petroleum ethers. GPC analysis the copolymers indicated weight-average molecular masses 10.7- 27.8kD (Table 1). According to elemental analysis, between 18.3 & 42.6 mol% of PPCA monomer is present in the copolymers prepared at EB/PPCA = 3 (mol), which is indicative of relatively high reactivity of the monomers towards EB. Results of DSC and TGA analyses are presented in Table 1.

The FTIR spectra of the monomers were compared with those of copolymers and poly(ethynylbenzene) thus providing evidence that the reaction between the PPCA monomers and EB is a copolymerization. The spectra of the copolymers show overlapping bands in 3200–2820cm-1 region corresponding to C-H stretch vibrations. The bands for the PPCA monomer unit are 2246–2238 (w, CN), 1752–1733 (s, C=O), and 1252–1226cm-1 (m, C-O). Benzene rings of both monomers show ring stretching bands at 1500–1400cm-1 as well as a doublet 824–715cm-1, associated with C-H out of plane deformations. These bands can be readily identified in ethynylbenzene copolymers with TSE monomers containing cyano and carbonyl electron withdrawing groups.

EB-PPCA copolymers microstructure analysis is based on 1H and 13C NMR spectroscopy (DEPT, HETCOR, NOESY and JMODXH) of EB copolymers with 2-phenyl-1,1-dicyanoethene [9] which showed the formation of both head-to-tail and headto- head alternating monomer structures, as well as short EB sequences.

Conclusion

Novel phenyl-disubstituted propyl 2-cyano-3-phenyl-2-propenoates were prepared and copolymerized with ethynylbenzene. The compositions of the copolymers were calculated from nitrogen analysis and the structures were analyzed by IR, H1 & 13C-NMR. The thermal gravimetric analysis indicated that the copolymers decompose in in two steps, first in the 200–500C range with residue (1–3%wt), which then decomposed in the 500–800 ºC range.

Tertiary-Butyl Methacrylate Market to Develop Rapidly by 2026

Tertiary-Butyl Methacrylate is defined as a colorless liquid with an ester like odor. It is less dense than water and insoluble in water. It has the molecular formula C8H14O2. Its other chemical names are 85-07-9, tert-butyl 2-methylprop-2-enoate, methacrylic acid, tert-butyl ester, 2-Propenoic acid, etc.

Read Report Overview @

https://www.transparencymarketresearch.com/tertiary-butyl-methacrylate-market.html

Tertiary-butyl methacrylate undergoes a decomposition process where the thermal decomposition of poly (t-butyl methacrylate) results in three distinct reactions: depolymerization to monomer, ester decomposition to isobutene and poly(methacrylic acid), and liberation of water from the resulting acid to give poly(methacrylic anhydride) as the ultimate in volatile residue. Depolymerization occurs rapidly at first but is soon completely inhibited by the products of ester decomposition. Methacrylic acid units, on the other hand, can depropagate quite readily since monomeric methacrylic acid is always found among volatile products in trace amounts. The ester decomposition phase of the reaction exhibits autocatalytic properties, and this is shown to be due to a catalytic effect of acid units on the decomposition of adjacent ester units, for which a mechanism is proposed.

Factors such as rise in demand from end-use industries such as automotive and construction are major drivers of the Tertiary-Butyl Methacrylate market owing to its wide usage. Moreover, the increase in demand for tertiary-butyl methacrylate in LCD and LED flat screens is also propelling the Tertiary-Butyl Methacrylate market.
