Electrophilic trisubstituted ethylenes, where X, Y, Z are electro-negative substituents, CN, COOCH3, Cl, and F have been synthesized. They do not homopolymerize but readily undergo free radical copolymerization with electron-rich vinyl monomers such as styrene. The copolymers, obtained in reasonably high molecular weights, have glass transition temperatures in the 150-225 C. range, decomposed in the 225-275 range, and were soluble in many organic solvents.
