ABSTRACT:
Alloys of polycycloolefin polymers are produced by dissolving an ethylene-based functional polymer in at least one polycycloolefin monomer and polymerizing the mixture. Various polycycloolefin catalysts can be utilized. Often it is desirable to utilize bulk polymerization including reaction injection molding (RIM), liquid injection molding (LIM), reinforced reaction injection molding (RRIM), resin transfer molding (RTM), and the like. The alloys have improved properties such as impact strength, solvent resistance, as well as improved thermal aging properties such as retention of impact strength.
