UV STABLE, IMPACT RESISTANT, FLAME RETARDED ABS COMPOSITION CONTAINING ALIPHATIC RESIN ABSTRACT OF THE DISCLOSURE UV stable, impact resistant, flame retarded thermoplastic compositions are obtained by compounding ABS with aliphatic resin, Diels-Alder adduct of 2 moles of chlorocyclopentadiene and 1 mole of cyclooctadiene (commonly known as Dech Plus), antimony oxide and optionally with nitrile rubber and/or surfactant. Such compositions consist essentially by weight of from about 0.5 to about 10% of aliphatic resin, from 0% to about 5% nitrile rubber, from 0% to about 5% surfactant, from about 14% to about 30% Dech Plus, from about 4% to about 20% antimony oxide and from about 50% to about 80% ABS. The ABS constituent has an Izod Impact Strength of at least 1.5 foot-pounds per inch: the amounts of said aliphatic resin, said nitrile rubber and said surfactant being such as to provide an Izod Impact Strength in foot-pounds per inch of notch determined by ASTM D-256, of at least 2.0 in the thermoplastic composition. The compositions have Izod Impact Strengths ranging from up to 4 foot-pounds per inch and in most cases a V-O (UL94) flammability classification.
