Title: Emulsion polymerized silicone-acrylate rubber impact modifiers thermoplastic blends, and methods for making

Abstract: Melt extrudable grafts of emulsion polymerized silicone rubber and polyacrylate rubber hybrids have been found to be valuable impact modifiers for organic thermoplastic polymeric materials. Optimum impact modifier properties are achieved by employing as a source material, an emulsion polymerized silicone rubber made under semi-continuous, low shear process conditions.
