ABSTRACT:
A composition is disclosed comprising a bisbenzocyclobutene, a bismide and a free radical inhibitor. The free radical inhibitor is preferably phenothiazine. The presence of the free radical inhibitor enhances the toughness and high-temperature viscosity stability of bisbenzocyclobutene/bismaleimide copolymers.
