Mehrphasige Polymermischungen

摘要

Multiphase polymer mixtures contain (a) a polymer (A); (b) an A-B graft copolymer (B) made of a block A as stock and of at least one resilient block B as grafted lateral chain or vice-versa; (c) a B-C graft copolymer (C) made of a resilient block B as stock and of at least one block C as grafted lateral chain or vice-versa; and (d) at least one additional polymer (D) that differs from (A), (B) and (C) and is incompatible with polymer (A). Blocks A, B and C differ from each other, polymer (A) is compatible with block A and incompatible with block C, polymer (D) is compatible with block C and incompatible with block A, the resilient block B has a glass transition temperature below +20 DEG C and blocks A, B and C are incompatible with each other.
