Abstract: WHEREIN: R is CH3, C2H5 or CH(CH3)2 and X is a bond, an alkylene or alkylidene group with 1 to 5 carbon atoms, a cyclohexylene or cyclohexylidene radical and an average degree of polymerization of at least 55. These polycarbonates are prepared by reacting the alkali salt of the corresponding bisphenols with phosgene of the bichlorocarbonic acid esters of the bisphenols or of oligomeric carbonates of the bisphenols and initiating the reaction with from 10 to 200 mol percent based on the bisphenols of an aliphatic tertiary amine and carrying out the reaction for from about 0.1 to about 5 hours.

Polycarbonates are provided which have the repeating structural units:
