    Abstract: In a process for producing modified rubber moulding masses, a first mixture (A) that contains at least one alkyl acrylate or methacrylate (a) having the general formula (I), in which R stands for a hydrogen atom or a methyl group and R stands for an alkyl group with 1 to 32 carbon atoms, at least one first monomer (b) that forms radicals by thermal decomposition, and optionally a second or several other monomers (c), is in a first step polymerised into a rubber (B), preferably together with free radicals. In a second step, the thus obtained rubber (B) is mixed with a third or several other monomers (d), preferably dissolved or dipped therein, to form a second mixture (C), and in a third step the second mixture (C) is polymerised with free radicals into the modified rubber moulding mass (D).

    Abstract: A moulding material based on an impact-modified thermoplastic A, selected from ABS, ASA, high-impact polystyrene (HIPS), high-impact polymethylmethacrylate, high-impact PVC, polycarbonate, polyester carbonate, polyester, polyamide (nylon), polyphenylene ether, polyether ketone, polyether sulphone, polysulphone, polyoxyalkylene, polyarylene sulphide and mixtures thereof, containing a matting agent B comprising from 30 to 80 % by weight of an elastomeric graft base B1 comprising from 75 to 99.8 % by weight of an alkyl acrylate having 1 to 8 carbon atoms in the alkyl radical (B11), from 0.1 to 5 % by weight of a polyfunctional, crosslinking monomer (B12) and from 0.1 to 20 % by weight of a monomer containing one or more acid groups or from 49.9 to 99.9 % by weight of one or more dienes (B111), up to 50 % by weight of a further ethylenically unsaturated monomer (B112) and from 0.1 to 20 % by weight of a monomer containing one or more acid groups (B113), and from 20 to 70 % by weight of a graft shell (B2) comprising from 40 to 99.9 % by weight of a vinyl aromatic monomer (B21), up to 49.9 % by weight of a polar, copolymerisable, ethylenically unsaturated monomer (B22) and from 0.1 to 20 % by weight of a monomer containing one or more basic groups (B23), and a moulding material whose constituents B13 or B113 and B23 have been interchanged.

    Abstract: The invention relates to rubber-modified, high-impact moulding compositions containing, based on the sum of A, B1 and B2, A: from 70 to 98% by weight of a polymer matrix A, formed by free radical-initiated polymerisation of a mixture of from 60 to 90% by weight of styrene and from 10 to 40% by weight of acrylonitrile, and B1: from 1 to 29% by weight of a particulate, first graft polymer B1 distributed in the matrix and comprising a graft base of polybutadien and graft branches of a copolymer of styrene and acrylonitrile, having a mean particle size of from about 100 to 500 nm, B2: from 1 to 29% by weight of a particulate, second graft copolymer B2 distributed in the matrix and comprising a graft base of polybutadien and graft branches of a copolymer of styrene and acrylonitrile having a mean particle size of from 600 to 10000 nm, as obtained by preparing the two graft copolymers in solution and/or bulk and incorporating them into the polymer matrix in a conventional manner. e

    Abstract: In a process for producing modified rubber moulding materials, a first mixture (A) that contains at least one alkyl acrylate or methacrylate (a) having the general formula (I), in which R stands for a hydrogen atom or a methyl group and R stands for an alkyl group with 1 to 32 carbon atoms, a first monomer (b) with two or more double bonds and optionally a second or several other monomers (c), is in a first step polymerised into a rubber (B), preferably together with free radicals. In a second step, the thus obtained rubber (B) is dissolved into or swollen with a third or several other monomers (d), optionally with admixture of a solvent, and in a third step, the second mixture (C) obtained by dissolving or swelling is polymerised into the modified rubber moulding material (D).
