Novel octyl 2-cyano-3-phenyl-2-propenoates, RPhCH=C(CN)CO2CH2(CH2)6CH3 (where R is 2-acetyl, 2,3,4-trimethoxy, 2,4,5-trimethoxy, 2,4,6-trifluoro, 3,4,5-trifluoro, 2,3,5,6-tetrafluoro, 2,3,4,5,6-pentafluoro, 3-bromo-4,5-dimethoxy, 5-bromo-2,3-dimethoxy, 3-chloro-2,6-difluoro) were prepared and copolymerized with styrene. The propenoates 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. The propenoates were copolymerized with styrene in solution with radical initiation (ABCN) at 70C. The compositions of the copolymers were calculated from nitrogen analysis. |
