HIGH HEAT POLYCARBONATES

摘要

A series of new high heat polycarbonate copolymers have been prepared and commercialized. These transparent resins extend polycarbonate heat capability beyond 200℃ while maintaining excellent melt processability, good mechanical properties and strength as well as practical toughness and flame resistance. In addition, the copolymers demonstrate useful optical properties including low birefringence and high refractive index, which may be useful in lighting and lens applications. The new resins may be blended with a variety of additives, such as fiberglass, to make a family of amorphous high heat resins.
