ABSTRACT:
A method is provided for making silicone-polyphenylene ether graft copolymers by oxidatively coupling a 2,6-dialkylphenol to a monophenol substituted organopolysiloxane macromer which can be prepared by the hydrosilylation of a phenol having a nuclear bound aliphatically unsaturated radical and a monohydrogen organosiloxane.
