THERMOPLASTIC POLYESTER COMPOSITIONS HAVING IMPROVED RELEASE PROPERTIES A reinforced, flame retardant molding composition based on polyalkylene terephthalate were found to be imparted an improved level of mold release properties upon the incorporation therein of a sufficient amount of a compound conforming to the structure of wherein R is a hydrocarbon derivative of a polyhydric alcohol preferably ethylene glycol, glycerol or pentaerythritol, R1 is hydrogen or a lower alkyl, n is about 10 to 30 and x is 2, 3 or 4. |
