ABSTRACT:
Copolycarbonate resins are prepared from an aromatic diol and a carbonic acid derivative. 2,2-bis(p-hydroxy-phenyl) 1,1,1,3,3,3-hexafluoropropane is co-reacted in a minor amount with the aromatic diol and carbonic acid derivative to form a polycarbonate having improved heat distortion characteristics.
