Abstract:
Composites of a macrocyclic oligomer and expanded graphite particles are prepared. The expanded graphite particles are easily incorporated into the composite at useful levels to provide desirable properties such as good heat distortion temperatures, good heat resistance, and sufficient electroconductivity to make the composite suitable for painting in electrostatic coating processes. The expanded graphite is characterized in having a very low bulk density and high surface area.

Abstract:
The present invention provides a light diffusing thermoplastic resin composition comprising polycaprolactone, specific silicone rubber particles, and, when desired, a fluorescent brightening agent, an antioxidant and/or an ultraviolet light absorber. A light diffusion sheet can be obtained by molding the light diffusing thermoplastic resin composition, which has superior light diffusion properties, luminance, mechanical strength, thermal stability and light resistance.
Abstract:
Crosslinked polydicyclopentadiene polymer and copolymer are made by first forming a thermoplastic polymeric intermediate in a ring-opening metathesis polymerization (ROMP), and then crosslinking the intermediate in a melt-processing or solution processing step. The formation of the intermediate permits facile removal of residual monomer, which leads to a reduction in odor and improvement in physical properties. Crosslinking can be achieved using various crosslinking strategies, including further ROMP reactions, addition polymerization of residual double bonds, addition of a crosslinking agent or introduction of functional groups.
