Abstract:
1. A curable composition, comprising: a capped poly(arylene ether) prepared by the reaction of an uncapped poly(arylene ether) with an anhydride capping agent; wherein the uncapped poly(arylene ether) comprises poly(2,6-dimethyl-1,4-phenylene ether), poly(2,6-dimethyl-1,4-phenylene ether-co-2,3,6-trimethyl-1,4-phenylene ether), or a mixture thereof; and wherein preparing the capped poly(arylene ether) further comprises precipitating the capped poly(arylene ether) by adding a solution of the poly(arylene ether) to isopropanol; and an olefinically unsaturated monomer; wherein the composition after curing absorbs less than 1 weight percent water after 7 days at 85° C. and 85% relative humidity.
