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 and (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 methyacrylic acid or acrylic acid and (c2) 0 to 50 wt. % of at least one monofunctional comonomer and (D) 0.1 to 15 wt. % of a block polymer made of (d1) 5 to 85 wt. % of ethylene oxide units and (d2) 95 to 15 wt. % of propylene oxide units, with a mean molar weight of 800 to 10,000 g/mol, whereby the blocks are coupled via a glycol derivative or glycerine derivative, whereby the total sum of the components amounts to 100 wt. %. The invention also relates to a method for producing said thermoplastic moulding materials and to the use thereof.
