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 1):
A poly(ester-carbonate) copolymer, comprising\n carbonate units of the formula and\n ester units of the formula \n wherein:\n T is a C 2-20  alkylene, a C 6-20  cycloalkylene, or a C 6-20  arylene; and \n R 1  and J are each independently\n (a) a bisphenol A divalent group of the formula \n \n and\n (b) a phthalimidine divalent group of the formula \n wherein\n R a  and R b  are each independently a C 1-12  alkyl, C 2-12  alkenyl, C 3-8  cycloalkyl, or C 1-12  alkoxy, each R 3  is independently a C 1-6  alkyl, R 4  is hydrogen, C 1-6  alkyl, or phenyl optionally substituted with 1 to 5 C 1-6  alkyl groups, preferably wherein R 4  is hydrogen, methyl, or phenyl, p, q, and j are each independently 0 to 4, \n provided that\n the phthalimidine group (b) is present in an amount of 40 mol % to 50 mol % based on the total moles of the bisphenol A divalent groups (a) and the phthalimidine groups (b); the ester units are present in an amount of 40 mol % to 60 mol % based on the sum of the moles of the carbonate units and the ester units; and \n wherein\n the poly(ester-carbonate) copolymer has a weight average molecular weight of 18,000 Daltons to 24,000 Daltons, as measured by gel permeation chromatography, using a crosslinked styrene-divinylbenzene column and calibrated to bisphenol A homopolycarbonate references; and \n a molded sample of the composition has\n a glass transition temperature of 210\u00b0 C. to 235\u00b0 C. as determined by differential scanning calorimetry (DSC) as per ASTM D3418 with a 20\u00b0 C./min heating rate; and \n a melt viscosity of less than 1050 Pa\u00b7s at 644 sec-1 and 350\u00b0 C., determined according to ISO11443.
