Emulsion polymerized silicone rubber-based impact modifiers, method of making, and blends thereof

摘要

A method is provided for making emulsion polymerized silicone rubber having an average particle size of from about 400 nm to 2 microns and grafts thereof. Thermoplastic blends having improved weatherability and impact strength are also provided based on the use of a thermoplastic organic polymer and a graft of such emulsion polymerized silicone rubber as an impact modifier.
