Zusammenfassung:	PURPOSE:A conjugated diene-vinyl aromatic hydrocarbon block copolymer composition, having excellent weatherability and color, made by incorporating a higher fatty acid in combination with a hindered amine compound therein. CONSTITUTION:0.05-5pts.wt. higher fatty acid (e.g. capric, stearic, or tallow fatty acid) and 0.005-3pts.wt. hindered amine compound (e.g. 4-acetoxy-2,2,6-tetramethylpiperidine) are incorporated into 100pts.wt. conjugated diene-vinyl aromatic hydrocarbon block copolymer (e.g. a block copolymer with a molecular weight of about 5,000-1,000,000 consisting of about 5-95wt% butadiene and about 95-5wt% styrene). In addition, a benzophenone compound or a benozotriazole compound may also be incorporated together.
