Thermoplastische Formmassen

摘要

The invention relates to thermoplastic moulding materials which essentially contain (A) 20 to 99 wt. % of at least one graft copolymer, (B) 1 to 80 wt. % of a copolymer that can be obtained from at least one alpha-olefin and at least one polar comonomer with the proviso that vinyl acetate or a vinylaromatic monomer are not used as monomers, (C) 0 to 80 wt. % of a thermoplastic polymer that can be obtained by polymerisation of a monomer mixture which essentially consists of (c1) 50 to 100 wt. % of at least one vinylaromatic monomer and/or one C1-C8-alkyl ester of methacrylic acid or acrylic acid and (c2) 0 to 50 wt. % of at least one monofunctional comonomer, (D) 0.5 to 30 wt. % of a (co)polymer made of (d1) 50 to 100 wt. % isobutylene and (d2) 0 to 50 wt. % of one or more additional monomers, whereby the total sum of the components (A) to (D) amounts to 100 wt. %. The invention also relates to a method for producing the thermoplastic moulding materials and to the use thereof.
