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.

Abstract: A method of manufacturing an electrostatic dissipating material (and compositions derived therefrom), wherein the method relates to:heat mixing or blending a first, a second and a third component in two steps, whereby in the first step the second and third components are first heat mixed or blended together to provide an initial mixture, and in a second step the first component is heat mixed or blended with said initial mixture,the first component is a polyolefinic, urethane, condensation, vinylic or styrenic polymer, the second component is a oxirane copolymer, and the third component is a polymer additive.
