Abstract
Amphiphilic block and graft copolymers with polysiloxane and poly[(ace tylimino)ethylene] sequences were used as nonionic surfactants in the emulsion polymerization of some vinyl monomers (styrene, methyl methac rylate, butyl methacrylate). The peculiarities of the systems (polymer ization kinetics and emulsion characteristics) were related to the str uctural features of the studied emulsifiers and suggested their abilit y to participate in initiation and transfer reactions and respectively clouding phenomena in aqueous phase.
