Difficult to mold polyester resin containing compositions are made thermoplastically moldable by the addition of an aromatic polycarbonate and mold-release additives of the formula: R-Y wherein R is selected from saturated and unsaturated hydrocarbyl having 13 to 44 carbon atoms, inclusive; and Y is selected from monovalent moieties of the formulae: -H, -COOR', and -O-R'' wherein R' is selected from hydrogen and hydrocarbyl of 1 to 36 carbon atoms, inclusive; and R'' represents one of lower alkyl and lower alkenyl.
