Abstract
A curable composition includes a functionalized poly(arylene ether), an olefinically unsaturated monomer, about 0.2 to about 5 parts by weight of a curing initiator per 100 parts by weight total of the functionalized poly(arylene ether) and the olefinically unsaturated monomer, and about 0.005 to about 1 part by weight of a curing inhibitor per 100 parts by weight total of the functionalized poly(arylene ether) and the olefinically unsaturated monomer. The weight ratio of the curing initiator to the curing inhibitor is about 1.2:1 to about 50:1. The composition provides improved and reproducible flow during the early stages of molding without compromising curing time. The composition is useful for preparing plastic-packaged electronic devices.
