Abstract
The invention discloses methods of preparing copolymers from norbornene-type monomers and cationically polymerizable monomers or polymers from catalytically polymerizable monomers by employing Group VIII transition metal ion source in a solvent for said monomers at a temperature in the range from -100.degree. C. to 120.degree. C. Also disclosed are copolymers from norbornene-type monomers and catalytically polymerizable monomers.
