The goals for this work are to get a better understanding on the emulsion polymerization of polysiloxane-modified-polyacrylate, which was used as an important composite in civic buildings' outside-wall-dope. Poly(siloxane/acrylate) was synthesized by emulsion polymerization by using octamethyltetracyclosiloxane (D4), 3-(trimethoxylsilyl)propyl methacrylate (MATS)- BA. MMA and AA as raw materials, potassium peroxydisulfate , OS/AP065 as initiator and emulsifiers respectively. This study was divided into two ...
