Abstract
A composition including a (poly)isocyanate compound and a capped poly(arylene ether) copolymer, wherein the capped poly(arylene ether) copolymer is derived from reacting a capping agent and an uncapped poly(arylene ether) copolymer comprising a phenolic end group, the uncapped poly(arylene ether) copolymer is the product of oxidative copolymerization of a monomer comprising a monohydric phenol, a dihydric phenol, or a combination thereof, and optionally a hydroxyaromatic terminated siloxane, and the capped poly(arylene ether) copolymer comprises an end group comprising an aliphatic alcohol.
