Abstract

A curable composition includes an olefinically unsaturated monomer and a poly(arylene ether) having two polymerizable groups and an intrinsic viscosity of about 0.05 to about 0.30 deciliters per gram. The composition exhibits an improved combination of high flow during molding and high post-cure stiffness and impact strength. The composition is particularly useful for fabricating plastic-packaged electronic devices.
