ABSTRACT:
A process is disclosed for preparing a blend of a metathesis polymer and a radical polymer wherein a norbornene polymer is metathesis polymerized in the presence of a vinyl compound having two double bonds in conjugated relationship. Also included in the system is a compound capable of being reduced to a radical by the reduced valence transition metal element which serves as the catalyst of the metathesis polymerization. Examples of such compounds are specific chlorinated organic and chlorinated inorganic compounds.
