    Abstract: New thermoplastic moulding material contains the following components: (A) 20-99 wt.,% at least one graft copolymer comprising 30-90 wt.% core (a1) prepd. by polymerisation of a mixt. of 80-99.9 wt.% at least one acrylic acid 1-10C alkyl ester (a11), 20 - 0.01 wt.% copolymerisable, polyfunctional, cross-linking monomer (a12) and 0 - 40 wt.% additional copolymerisable, monoethylenic unsatd. monomer (a13), with 70 - 10 wt.% graft component (a2) prepd. by polymerisation in the presence of (a1) of a monomer mixt. comprising 50 - 100 wt.% styrene cpd. of formula (I) and/or (meth)acrylic acid 1-8C alkyl ester (a21) and 50 - 0 wt.% monofunctional comonomer (a22); (B) 80 - 1 wt.% copolymer prepd. from at least one alpha-olefin and at least one polar comonomer, except vinyl acetate or vinyl aromatic monomers; and (C) 0 - 50 wt.% thermoplastic polymer prepd. by the polymerisation of 50 - 100 wt.% vinyl aromatic monomer and/or (meth)acrylic acid 1-8C alkyl ester (c1) and 50 - 0 wt.% monofunctional comonomer (c2), all wrt. sum of (A), (B) and (C); R1, R2 = H or 1-8C alkyl. Also claimed are (i) prepn. of the moulding material by mixing (A), (B) and (C), (ii) use of the material for the prepn. of moulded articles or films, (iii) films or moulded articles prepd. from the material, and (iv) films with a leather-like appearance.

    Abstract: The present invention relates to moulding compositions based on polymethyl methacrylate, essentially containing A) from 99.99 to 95.0% by weight of a mixture essentially comprising a1) from 5 to 95% by weight of polymethyl methacrylate, obtainable by polymerisation of a mixture essentially comprising a11) from 80 to 100% by weight of methyl methacrylate and a12) from 0 to 20% by weight of a C1-C20-alkyl ester of acrylic acid, and a2) from 95 to 5% by weight of a multistep graft copolymer based on a C1-C20-alkyl ester of acrylic and/or methacrylic acid, and B) from 0.01 to 5.0% by weight of a polysiloxane of the formula I in which R is C1-C6-alkyl or C6-C10-aryl, R is hydroxy-C1-C6-alkyl or amino-C1-C6-alkyl, and n is a natural number from 5 to 200. d
