James T Ware, Robert J Minchak: Method for enhancing the polymerization activity of crude cycloolefin monomers for bulk polymerization. The B F Goodrich Company, Robbins & Laramie, June 27, 1989: US04843185 (3 worldwide citation)

A process for enhancing the polymerization activity of mixtures of one or more cycloolefin monomers is provided by treatment with heat. This process can be easily incorporated into ring-opening, bulk polymerization methods and methods which form high molecular weight monomers. Enhancing the polymeri ...
