In this thesis, the development of emulsion polymerization theory and related new technologies are comprehensively reviewed, and the synthetic technologies of acrylate latex modified by organosilicon both at home and abroad are also reviewed. based on the current development and research in this field, attentions of this study are focused on three ways for preparing novel acrylate latexes modified by organosilicons, that is, 1 ) the acrylate monomers are copolymerized with unsaturated silicons by emulsion copolymerization ; 2 ) a new latex with microphase separation morphology is synthesized, which shows a core - shell structure character ; 3 ) soap - free polymerization is explored for preparing a higher - performance latex using an unsaturated silicon monomer, different acrylates and a reactive emulsifier. by using techniques of delaying addition of organosilicon monomer and a hydrolysis inhibitor, the hydrolysis and condensation of 3 - ( trimethoxysilyl ) propyl methacrylate during polymerization can be effectively prevented, as a result, organosilicon content in the macromolecular chain is increased
