摘要
Via the conventional emulsion copolymerization of acrylic monomers and vinyl-containing alkoxysilane monomers with three siloxane groups, siloxane groups were added to acrylic copolymers to make alkoxysilane-functionalized acrylic copolymer latexes. In producing stable polymer latexes, seeded polymerization was superior to the other two processes, batch and continuous addition polymerization. The experimental results showed that vinyltriethoxysilane-acrylic copolymer latexes were capable of film forming. In contrast, the incorporation of methacryloxypropyl trimethoxysilane gave rise to the formation of highly crosslinked acrylic copolymer latexes, which had poor film-forming properties. Relatively small monodispersed particles with particle sizes of less than 100 nm. were formed. These particles had a core-shell structure, although some of them were asymmetric.
