Mit alpha-Tocopherol, einem organischen Phosphit und einem sterisch gehinderten Phenol stabilisierte Styrol/Butadien-Blockcopolymere |
摘要 |
Disclosed is a molding composition made from linear or star-shaped styrene/butadiene block copolymers produced by anionic polymerization, of general structure (A)m-X, wherein A is a block copolymer section consisting of at least one polystyrene block with a molecular mass of 3,000 to 230,000 (g/mol) and a polybutadiene block with a molecular mass of 2,000 to 30,000 (g/mol), with A having a total molecular mass of 5,000 to 300,000 (g/mol), the block transitions are sharp or blurred and, to prevent decomposition due to light, atmospheric oxygen and/or heat, the molding composition contains 0.01 to 1 wt.% alpha -tocopherol, 0.1 to 2 wt.% organic phosphite of the general formula RO3P, in which R is alkyl, aryl or cycloalkyl, and 0.01 to 2 wt.% sterically hindered phenol.
