Polystyrene modified with silicone rubber powder. |
摘要 |
<p>A crumb-like silicone rubber powder is uniformly dispersed in a polystyrene polymer using conventional equipment, such as a twin screw extruder, to provide a resin having up to a ten fold improvement in impact strength over the unmodified polymer. The novel silicone rubber powder of the invention is prepared by isolating the particles obtained from a polymerization of an unsaturated monomer in the presence of an aqueous emulsion of a hydroxyl-functional polydiorganosiloxane which has been precured using an organotin curing catalyst and a crosslinker which contains unsaturated functionality.</p> |
