Abstract:
A poly(ester-carbonate) copolymer comprises carbonate units of the formula (I); and ester units of the formula (II) wherein: T is a C 2-20  alkylene, a C 6-20  cycloalkylene, or a C 6-20  arylene; and R1 and J are each independently a bisphenol A divalent group and a phthalimidine divalent group, provided that the phthalimidine divalent group is present in an amount of 40 to 50 mol % based on the total moles of the bisphenol A divalent groups and the C  1/2  divalent group, and the ester units are present in an amount of 40 to 60 mol % based on the sum of the moles of the carbonate units and the ester units; and wherein the poly(ester-carbonate) copolymer has a weight average molecular weight of 18,000 to 24,000 Daltons; and the composition has a Tg of 210 to 235° C. and a melt viscosity of less than 1050 Pa-s at 644 sec −1  and 350° C.

Claim (Index 3):
The poly(ester-carbonate) copolymer of  claim 1 , wherein the poly(ester-carbonate) copolymer comprises phthalimidine divalent groups (b) and the mol % of the phthalimidine divalent groups, the mol % of the ester units, and the weight average molecular weight of the poly(ester-carbonate) copolymer are selected according to the following formula:\n Tg= 127.1+(0.94375\u00d7Mol %  PPP )+(0.3875\u00d7Mol % Ester)+(0.00164968\u00d7 Mw ).
