Abstract

An alkali metal or alkaline earth metal nitrite is added to a polymer blend comprising (1) block copolymer formed from monovinyl-substituted aromatic hydrocarbon monomer and a conjugated diene monomer and (2) styrene polymer to improve thermal stability and to inhibit gel and fisheye formation.
