Vinyl polymerization. 413. Polymerization of vinyl monomer initiated by poly(vinylbenzyltrimethyl)‐ammonium chloride

Abstract

SynopsisThe polymerization of vinyl monomer initiated by an aqueous solution of poly(vinylbenzy1trim-ethy1)ammonium chloride (Q-PVBACl) was carried out at 85OC. Styrene, p-chlorostyrene, methyl methacrylate, and i-butyl methacrylate were polymerized, whereas acrylonitrile and vinyl acetate were not. The effects of the amounts of vinyl monomer, Q-PVBAC1, and water on the conversion of vinyl monomer were studied. The overall activation energy in the polymerization of styrene was estimated as 79.1 kJ mol-'. The polymerization proceeded through a radical mechanism. The selectivity of vinyl monomer was discussed by "a concept of hard and soft hydrophobic areas and monomers." ANAL. Calcd for --fC12HlgNCl j12~fCgHgCl juo+CgHg&-: C, 68.80%; H, 8.02%; N,
