Copolycarbonates, methods of manufacture, and uses thereof

1 f 1 55 A copolycarbonate of the formula wherein 5 to 50 mole percent of the total number of Rgroups is derived from a monomer of formula (2) wherein each Ris independently at each occurrence a halogen atom, a hydrocarbon group having 1 to 10 carbons, or a halogen substituted hydrocarbon group having 1 to 10 carbons, and n is 0 to 4; and 50 to 95 mole percent of the Rgroups are derived from a dihydroxy compound of formula HO-R-OH, wherein at least 60% of the Rgroups are aromatic, and the dihydroxy compound of formula (3) is not a compound of formula (2), and wherein the copolycarbonate comprises at least 10% fewer carbonate linkages of formula (4) than would be theoretically obtained in a random copolymer made from the same ratio of the monomer of formula (2) and the dihydroxy compound of formula (3).
