Preparation of Polysiloxane-Acrylic Composite Latexes having Core-Shell Structure

Revised Date: 29 November 1994

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 monomers on the formation of latex particles were investigated. The results showed that the emulgent amount on the particle surface of polysiloxane emulsions played an important role on the formation of the la-tex particles having core-shell structure. When the emulgent coverage on the surface of polysiloxane particles was less 40%, the polysiloxane-acrylic latexes where most particles possess core-shell structure may be produced.
