Abstract
Abstract Partially crosslinked, thermoplastic resin compositions prepared by dynamically heat-treating a thermoplastic resin, having substantially no carbon-carbon bond unsaturation, in the presence of: a dihydroaromatic compound as a crosslinking agent, said dihydroaromatic compound being selected from the group consisting of a 1,2-dihydroquinoline compound, a polymer thereof and 9,10-dihydrophenanthrene; and a polyfunctional monomer, such as a bismaleimide compound.
