Method for making polyarylene ether-siloxane copolymers

Prepn. of polyarylene ether copolymers, comprising contacting: (a) a polyarylene ether; (b) a hydroxyaromatic terminated siloxane reagent; and (c) an oxidant; whereby the polyarylene ether portion of the copolymer has a lower molecular wt. than the initial polyarylene ether. The process is useful fo...

Zusammenfassung:	Prepn. of polyarylene ether copolymers, comprising contacting: (a) a polyarylene ether; (b) a hydroxyaromatic terminated siloxane reagent; and (c) an oxidant; whereby the polyarylene ether portion of the copolymer has a lower molecular wt. than the initial polyarylene ether. The process is useful for preparing polyphenylene ether-siloxane copolymers.
