ABSTRACT:
A process for increasing the molecular weight of cycloolefin monomers is provided by this invention which can be incorporated into ring-opening polymerization methods. This method is particularly suited for bulk polymerization processes but can also be used for solution polymerization processes. By increasing the molecular weight of the cycloolefin monomers, polymers having higher glass transition temperatures are obtained.
