α-Cyanovinyl acetate (α-CN·VAc) is polymerized anionically at 70°C in the presence of pyridine, a weak base, although the presence of strong base such as butyllithium leads to decomposition of the monomer. The anionic polymerization accompanies radical polymerization at a relatively high temperature. Pyridine in concentration up to 0.12 mol/l works inhibitory for the radical polymerization of α-CN·VAc, while it serves efficiently as anionic catalyst in the presence of p-benzoquinone. The rate of the anionic polymerization is directly proportional to the concentration of pyridine. In the anionic bulk-copolymerization of α-CN·VAc (M1) and styrene (M2), pyridine-benzoquinone catalyst gives r1=10.0 and r2=0.01.
