Abstract: Poly(styrene-chloromethyl styrene-acrylie acid) latex particles of high specific gravity were prepared by emulsifier-free emulsion polymerization. Copolymerization and the properities of latex particles were effectively controlled by varying the molar ratio of monomers. The stable latex microspheres with excellent monodispersity and clear surface were obtained.

Key words: chloromethyl styrene, styrene, acrylic acid, emulsion copolymerization, microspheres
