Abstract
Electrophilic trisubstituted ethylene monomers, halogen ring substitut ed 2-cyano-3-phenyl-2-propenamicies, RC6H4CH=C(CN) CONH2 (where R is o -Cl, m-Cl, p-C, p-Br, and p-F) were prepared by Knoevenagel condensati on. Novel copolymers of the propenamides and styrene were prepared at equimolar monomer feed composition by solution copolymerization in the presence of a radical initiator at 80 degrees C. The order of reactiv ity (1/r(1)) for the monomers (M-1=styrene) was o-Cl (1.42) > p-F (1.1 9) > p-Cl (0.70) > m-Cl (0.60) > p-Br (0.44).
