Synthesis And Styrene Copolymerization Of Octyl 2-Cyano-3-(R-Phenyl)-2-Propenoates, Martin S. Wasilewski
Synthesis And Styrene Copolymerization Of Octyl 2-Cyano-3-(R-Phenyl)-2-Propenoates, Martin S. Wasilewski
College of Science and Health Theses and Dissertations
Novel alkyl ring-substituted octyl phenylcyanoacrylates (OPCA), RPhCH=C(CN)CO2CH2(CH2)6CH3, where R is H, 2-methyl, 3-methyl, 4-methyl, 4-ethyl, 4-propyl, 4-i-propyl, 4-butyl, 4-t-butyl, 4-i-butyl) were prepared and copolymerized with styrene. The ethylenes were synthesized by the piperidine catalyzed Knoevenagel condensation of ring-substituted benzaldehydes and octyl cyanoacetate, and characterized by CHN analysis, IR, 1H and 13C NMR. All the ethylenes were copolymerized with styrene in solution with radical initiation (ABCN) at 70°C. The compositions of the copolymers were calculated from nitrogen analysis. Compositions of ST-OPCA copolymers ranged from 18.6 % to 27.4% of …

Synthesis And Analysis Of Novel Copolymers Of Ring-Substituted 2-Phenyl-1, 1-Dicyanoethylenes And Styrene, Subha Ramnarayan
College of Science and Health Theses and Dissertations
Trisubstituted Ethylene (TSE) monomers, ring substituted 2-phenyl-1, 1-dicyanoethylenes are synthesized by knoevenagel condensation of ring substituted benzaldehyde with malononitrite, catalyzed by piperidine. TSE monomers are copolymerized with system by radical chain polymerization.
