Descrição: Novel trisubstituted ethylenes, fluorine ring-substituted butyl 2-cyano-3-phenyl-2-propenoates, RPhCHC˭(CN)CO 2 C 4 H 9 (where R is 2,3-diF, 2,4-diF, 2,5-diF, 2,6-diF, 3,4-diF, 3,5-diF, and 2,4,5-triF) were prepared and copolymerized with styrene. The monomers were synthesized by the piperidine catalyzed Knoevenagel condensation of ring-substituted benzaldehydes and butyl cyanoacetate, and characterized by CHN analysis, IR, 1 H and 13 C-NMR. All the ethylenes were copolymerized with styrene (M 1 ) in solution with radical initiation (ABCN) at 70°C. The compositions of the copolymers were calculated from nitrogen analysis and the structures were analyzed by IR, 1 H and 13 C-NMR. Decomposition of the copolymers in nitrogen occurred in two steps, first in the 200-500°C range with residue (1.5-2.3% wt.), which then decomposed in the 500-800°C range.
