    Abstract: A copolycarbonate comprises first repeating units, second repeating units different from the first repeating units, and third repeating units different from the first and second repeating units; and wherein the first repeating units are phthalimidine carbonate units, the second repeating units are carbonate units of the formula (I) wherein Rc and Rd are each independently a C1-12 alkyl, C2-12 alkenyl, C3-8 cycloalkyl, or C1-12 alkoxy, each R6 is independently C1-3 alkyl or phenyl; Xa is a C6-12 polycyclic aryl, C3-18 mono- or polycycloalkylene, C3-18 mono- or polycycloalkylidene, -(Q1)x-G-(Q2)y- group wherein Q1 and Q2 are each independently a C1-3 alkylene, G is a C3-10 cycloalkylene, x is 0 or 1, and y is 1; and m and n are each independently 0 to 4; and the third repeating units are carbonate units (II) wherein Re and Rf are each independently C1-12 alkyl, C2-12 alkenyl, C3-8 cycloalkyl, or C1-12 alkoxy, a and b are each independently integers of 0 to 4, and Xb is a single bond, —0—, —S—, —S(0)-, —S(0)2—, —C(0)—, or C1-32 bridging hydrocarbon group, provided that Xb is not a phthalimidine group or Xa.
