摘要： A copolycarbonate is discloses, comprising units of the formula (1) wherein 70 to 99.5 mole percent of the total number of R1 groups are derived from a dihydroxy compound of formula (2) wherein R2 and R3 are each independently a halogen or a Cj-6 alkyl group, R4 is a methyl or a phenyl group, and c is independently O to 4; and 0.5 to 30 mole percent of the total number of R1 groups are derived from a dihydroxy compound of formula (3) wherein at least 60% of the R3 groups are aromatic, and the dihydroxy compound of formula (3) is not the same as the dihydroxy compound of formula (2), and wherein the copolycarbonate has a glass transition temperature of 2500C or higher.

摘要： A polycarbonate such as aliphatic/aromatic polycarbonate comprises repeating structural carbonate units of the formula (H-I): in which Rh is a radical having the formula (H-2): wherein each of R11, R12, R13, R14, R15. R16, R17, R18, R19, R20, R2I, R22, R23, R24, R25, R26, R27, and R28 is independently a hydrogen, a C1-C6 alkyl group, or a halogen substituted C1-C6 alkyl group. The polycarbonate, and a thermoplastic composition thereof, have improved thermal stability, cost-effectiveness, and exhibit improved manufacturability such as, for example, minimum cyclic carbonate formation and minimum amine acceptor requirement.
