摘要：

Monodisperse latexes were synthesized by copolymerization of 23-98 % by weight styrene and 0-75 % vinylbenzyl chloride with 1 % divinylbenzene and 1 % (vinylbenzyl)trimethylammonium chloride using 2,2'-azobis(N,N'-dimethyleneisobutyramidine) dihydrochloride initiator at 60-degrees-C. Particle size in the range 100-200 nm in diameter was controlled via the amount of charged monomer used in the first stage of shot growth polymerization. Polydispersity indexes were D(w)/D(n) = 1.01. Treatment of the copolymers with trimethylamine produced latexes containing 1-60 mol % of (vinylbenzyl)trimethylammonium chloride repeat units.
