Patent ID: 7109274

Claim:
A polymer composition comprising: a transparent polymer blend, said transparent polymer blend comprising; (a) a first ITR resin, said first ITR resin comprising polyarylate structural units of formula I wherein R 1 is independently at each occurrence a C 1 –C 12 alkyl group, or a halogen atom, and p is 0 to 3; and (b) a second ITR resin, said second resin comprising polyarylate structural units I; said polyarylate structural units being present in an amount corresponding to a mole percentage of the total repeat units of said first ITR resin and a mole percentage of the total repeat units of said second ITR resin; said first ITR resin and said second ITR resin being characterized by a difference in polyarylate structural unit content, said difference being about 9 to about 40 mole percent.
