Patent ID: 7230065

Claim:
A polymer composition comprising: (A) from 1 to 99 percent by weight at least one polyester (A) comprising: (1) diacid residues comprising from about 80 to 100 mole percent diacid residues selected from the group consisting of terephthalic acid residues, isophthalic acid residues, and mixtures thereof; and from about 0 to about 20 mole percent of modifying diacid residues having about 2 to 20 carbon atoms, wherein the total mole percent of diacid residues is equal to 100 mole percent; and (2) diol residues comprising from about 50 to 65 mole percent 1,4-cyclohexanedimethanol residues, from about 1 to about 49 mole percent of ethylene glycol residues, from about 1 to 35 mole percent 2,2′-(sulfonylbis(4,1-phenyleneoxy)-bis(ethanol) and from about 0 to 10 mole percent modifying diol residues having from 3 to 16 carbon atoms, wherein the total mole percent of diol residues is equal to 100 mole percent; and (B) from 1 to 99 percent by weight of at least one polycarbonate (B) comprising from about 90 to 100 mole percent 4,4′-isopropylidenediphenol and from about 0 to 10 mole percent modifying diol residues having 2 to 16 carbon atoms, wherein the total mole percent of diol residues is equal to 100 mole percent; wherein the total weight percent of said polyester(s) (A) and polycarbonate(s) (B) is equal to 100 weight percent; and wherein the polyester(s) (A) and polycarbonate(s) (B) are miscible when blended together.
