Abstract

Abstract Translated from German Thermoplastische Formmasse, enthaltend, jeweils bezogen auf die Summe der Bestandteile A, B und C, A: 10 bis annähernd 90 Gew.-% eines Styrolpolymerisats A, B: 10 bis annähernd 90 Gew.-% eines Polyolefins B und C: 1 bis 20 Gew.-% eines durch anionische Polymerisation aus Styrol und Butadien und/oder Isopren hergestellten, unsymmetrischen linearen Dreiblockcopolymerisats C der Struktur S1-D-S2, wobei S1 und S2 je einen Polystyrolblock und D einen Polydienblock bezeichnet, dadurch gekennzeichnet, daß das Dreiblockcopolymerisat C einen Styrolgehalt, bezogen auf S, zwischen 50 und 85 Gew.-% aufweist und sich die aus Styrol aufgebauten Endblöcke S1 und S2 im Molekulargewicht um mindestens 50 % unterscheiden. Thermoplastic molding composition containing, based in each case on the sum of constituents A, B and C, A: 10 to approximately 90% by weight of a styrene polymer A, B: 10 to approximately 90% by weight of a polyolefin B and C: 1 to 20% by weight of an asymmetrical linear three-block copolymer C of structure S1-D-S2 produced by anionic polymerization from styrene and butadiene and / or isoprene, S1 and S2 each denoting a polystyrene block and D denoting a polydiene block, characterized in that the three-block copolymer C has a styrene content, based on S, of between 50 and 85% by weight and the end blocks S1 and S2 made of styrene differ in molecular weight by at least 50%.
