Abstract

1533008 Copolycarbonates DOW CHEMICAL CO 19 Aug 1976 [20 Aug 1975] 34555/76 Heading C3R A thermoplastic copolycarbonate having a weight-average molecular weight of from 25,000 to 60,000 is derived from a carbonate precursor and an aromatic diphenol comprising from 4À7 to 41À1 mole per cent of phenolphthalein. The examples describe copolycarbonates derived from phosgene, bisphenol A, phenolphthalien and p-tert-butylphenol.
