POLYESTER-POLYCARBONATE BLENDS
First Claim
1. A composition of matter comprising a thermoplastic resin composition derived fromi. about 20 weight percent to about 80 weight percent of a polyester derived from a diol comprising cyclohexane dimethanol and a diacid;
- ii. about 5 weight percent to about 80 weight percent of a copolycarbonate derived from about 20 weight percent to about 70 weight percent of a 2-hydrocarbyl-3,3-bis(hydroxyaryl)phthalimidine and from about 30 weight percent to about 80 weight percent of a second aromatic dihydroxy compound;
iii. about 0 weight percent to about 70 weight percent of a thermoplastic resin, C wherein the thermoplastic resin C is selected from the group consisting of a homopolycarbonate, a poly(estercarbonate), a poly(arylatecarbonate) and combinations thereof, andwherein the resin composition is transparent.
