Homopolymerization of acrylate or methacrylate endblocked polydiorganosiloxanes |
摘要 |
Method for homopolymerization of polyorganosiloxane macromonomers having acryloxy or methacryloxy groups. A miniemulsion of a methacryloxy functional polydimethylsiloxane macromonomer was prepared by mixing the macromonomer with a surfactant(s), and subjecting it to a high shear device. The macromonomer was polymerized in the miniemulsion by using a free radical initiator at high temperature. The amount of unreacted macromonomer is very low.
