Abstract
Linear indane polycarbonate polymers, both homopolymers and copolymers derived from biphenols and bisphenols are disclosed. The indane polycarbonates have high glass transition temperatures and exhibit good mechanical properties, good thermal stability, and good ductility even at temperatures greater than 150.degree. C. making them useful for high temperature processing applications. In addition, the clear indane polycarbonate compositions exhibit good optical properties.
