| Alkoxy ring-substituted 2-phenyl-1,1-dicyanoethylenes, RC6H4CH=C(CN)2, (where R is 2-methoxy, 3-methoxy, 4-methoxy, 3-ethoxy, 4-ethoxy, 4-propoxy, 4-buthoxy, and 4-hexyloxy) were prepared via a piperidine catalyzed condensation of appropriate substituted benzaldehydes and malononitrile. The radical copolymerization of the monomers with vinyl acetate at equimolar monomer feed results in equimolar alternating copolymers. The composition of the copolymers was calculated from nitrogen analysis, the structure and properties were analyzed by IR, 1H- and 13C-NMR, GPC, DSC, and TGA.
