Difficult to mold polyester resin containing compositions are made thermoplastically moldable by the addition of a polycarbonate resin and polymer mold-release additives of the formula:- <CHEM> wherein X is selected from the group consisting of hydrogen and halogen; Y represents hydrogen, halogen or a monovalent moiety of the formula: <CHEM> wherein R represents hydrocarbyl of 4 to 36 carbon atoms, inclusive; m is an integer of 0 to 1, provided when Y is not hydrogen or halogen m is 0; and n is an integer such that the polymer has a molecular weight of from about 400 to about 150,000. |
