Abstract

Abstract: Polysiloxane-acrylic composite latexes having core-shell structure were prepared stepwisely by seeded emulsion polymerization.The effects of emulgent's coverage extent on latex particle surface,addition method of emulgent and ratio of mononiers on the formationof latex particles were investigated.The results showed that the emulgent amotint on theparticle surface of polysiloxane emulsions played an important role on the formation of the latex particles having core-shell structure.When the emulgent coverage on the surface ofpolysiloxane particles vvas less 40%,the polysiloxane-acrylic latexes where most particlespossess core-shell structure may be produced.

Key words: polysiloxane latex, acrylic ester, Core-shell structure, emulsion polymerization
