PHASE-SEPARATING BLOCK COPOLYMERS COMPOSED OF INCOMPATIBLE HARD BLOCKS AND MOLDING MATERIALS WITH HIGH STIFFNESS
摘要：
A block copolymer with weight-average molar mass Mw of at least 100 000 g/mol, comprisinga) at least one block S composed of from 95 to 100% by weight of vinylaromatic monomers and from 0 to 5% by weight of dienes, andb) at least one copolymer block (S/B)A composed of from 63 to 80% by weight of vinylaromatic monomers and from 20 to 37% by weight of dienes, with glass transition temperature TgA in the range from 5 to 30° C., andc) at least one copolymer block (S/B)B composed of from 20 to 60% by weight of vinylaromatic monomers and from 40 to 80% by weight of dienes, with glass transition temperature TgB in the range from 0 to −80° C.,where the proportion by weight of the entirety of all of the blocks S is in the range from 50 to 70% by weight, and the proportion by weight of the entirety of all of the blocks (S/B)A and (S/B)B is in the range from 30 to 50% by weight, based in each case on the block copolymer A, and also mixtures thereof, and their use.
