  • Homogeneous addition copolymers of ethylene and cycloolefin monomers and method for producing same
    Patent number: 4948856
    Abstract: The present invention provides a method for producing addition copolymers of ethylene and cycloolefin monomers of the norbornene-type, such as norbornene and tetracyclododecene. Copolymers having a uniform structure with uniform glass transition temperature values are provided by performing the copolymerization reaction in bulk with a catalyst system soluble in the cycloolefin monomers.

  • Method for enhancing the polymerization activity of crude cycloolefin monomers for bulk polymerization
    Patent number: 4843185
    Abstract: 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 polymerization activity of crude mixtures of cycloolefin monomers by this process permits polymers having higher glass transition temperatures and higher heat distortion temperatures to be produced with greater economy.
