MISCIBLE TRANSPARENT BLENDS OF AROMATIC POLYCARBONATES WITH POLYCARBONATE POLYMERS CONTAINING HIGH ASPECT RATIO MONOMERS

摘要

The present invention relates to a miscible transparent polymer blend, specifically, a polycarbonate blend which comprises homopolycarbonates and/or copolycarbonates. In particular, high aspect ratio monomers confer unique miscibility properties on polycarbonates. Miscible, transparent blends have been found to form from polycarbonate mixtures containing as components of the mixture (1) polycarbonates of bisphenol A monomers copolymerized with a variety of bisphenols, and (2) polycarbonates containing high aspect ratio monomers.
