Thermally stable blends of polyphenylene ether and diene based rubber.

摘要

There are provided melt extruded blends of polyphenylene ether and diene based rubber containing an effective amount of a dialkylamine which has been found effective as a stabilizer for the diene based rubber. Additional diene based rubber stability can be achieved by using preextruded polyphenylene ether. The resulting melt extruded blends have been found to enjoy increased resistance to change in impact values when recycled in the molded state.
