Abstract:
A thermoplastic molding composition consisting essentially of components A, a polyester, and component B, a mold release agent, and, optionally, components C, D and/or E as follows:a) as component A, from 40 to 99.99% by weight of at least one polyester based on poly-C2-C6-alkylene terephthalates, b) as component B, from 0.01 to 3% by weight of glycerol bis (fatty acid) esters of C12-C24-fatty acids, wherein the fatty acids may have a hydroxyl group and from 1 to 3 carbon-carbon double bonds, c) as component C, from 0 to 49.99% by weight of blend polymers miscible with component A or dispersible therein, d) as component D, from 0 to 50% by weight of fillers, and e) as component E, from 0 to 10% by weight of other additives, selected from the group consisting of UV stabilizers, oxidation retarders, dyes, pigments, colorants, nucleating agents, antistats, antioxidants, stabilizers to improve thermal stability, to increase light stability, or to raise hydrolysis resistance and chemicals resistance, agents to prevent decomposition by heat, and in addition to said mold-release agent, lubricants useful for producing moldings wherein the total percentages add up to 100%.
