Abstract: The invention relates to a thermoplastic moulding composition built up from a copolymer A and an aromatic polyester B. The (co)polymer A comprises predominantly methyl methacrylate and is present in a proportion of from 1 to 15% by weight, based on the moulding composition of A + B. The aromatic polyester comprises b1) from 10 to 90 mol%, based on B, of recurring units of the general formula in which: -X- is -O-, -S-, -SO2-, -SO-, -CO-, an alkylene group having 1 to 4 carbon atoms and/or an alkylidene group containing 1 to 4 carbon atoms, R , R , R , R , R' , R' , R' and R' , which may be identical or different, are a hydrogen atom, a chlorine atom, a bromine atom or an alkyl group having 1 to 4 carbon atoms, and b2) from 90 to about 10 mol% of recurring units of the general formula in which -X-, R , R , R , R , R' , R' , R' and R' are as defined above. Component B is used in a proportion of from 85 to 99% by weight, based on the moulding composition. The moulding composition may optionally contain conventional additives and is used for the production of mouldings.

Abstract: The invention relates to a thermoplastic moulding composition comprising from 50 to 90% by weight of a copolymer A and from 10 to 50% by weight of a rubber B. The copolymer A is built up from 65 to 95% by weight of a monovinylaromatic monomer and from 5 to 35% by weight of an unsaturated dicarboxylic anhydride. The rubber B has a glass transition temperature, Tg, of /=200 DEG C. The moulding composition is used to produce mouldings.

Abstract: A thermoplastic moulding composition which is a mixture of 5-95% by weight of an impact-modified styrene-maleic anhydride copolymer (I) and 95-5% by weight of a polycarbonate (II). The impact-modified styrene-maleic anhydride copolymer (I) is a mixture of two constituents A and B. It contains from 50 to 95% by weight of a copolymer A, based on A + B, which is built up from: a1) from 65 to 95 parts by weight of a monovinylaromatic monomer, a2) from 5 to 35 parts by weight of an unsaturated dicarboxylic anhydride, optionally a3) from 2 to 15 parts by weight of an acrylically unsaturated monomer. Constituent B is present in a proportion of 5 to 50% by weight, based on A + B, and is a graft copolymer built up from: b1) from 50 to 90 parts by weight of a rubber which has a glass transition temperature, Tg, of below 0 DEG C, b2) from 10 to 50 parts by weight of a monovinylaromatic monomer, and b3) from 0.1 to 25 parts by weight of a (meth)acrylate and/or acrylonitrile, where, regarding the parts by weight of the monomers building up the hard matrix and the graft shell, the absolute values of the difference of the parts by weight between the sum of [a2) and a3)] and [b3)] differ by 4 or less than 4. The moulding composition according to the invention is prepared by mixing the constituents component I with component II in the melt. The moulding compositions according to the invention are used for the production of mouldings.

Abstract: The invention relates to moulding compositions comprising a) polyphenylene ethers and b) impact-modified styrene polymers, which are characterised in that they i) contain impact-modified styrene polymers whose soft component has a mean particle diameter of greater than 0.2 mu m, with the proviso that a substantial amount of the soft component has a particle diameter of greater than 3 mu m, and ii) contain a polyorganosiloxane as a further component. Such moulding compositions have a balanced property profile with respect to toughness, both in the notched impact strength test and in the falling tube test, and flow properties.

Abstract: A thermoplastic moulding compsn. comprises an impact resistant styrene polymer (I) contg. a matrix with a wt. ave. mol. wt. (GPC) of greater than 270000 and a mol.wt. distribution of 3 or less and a polyphenylene ether (II). The compsn. comprises 5-90 pref. 20-80 wt.% (I) and 95-10 pref. 80-20 wt.% (II). (I) are prepd. by polymerisation of monovinyl aromatic monomers in the presence of a rubber. The amt. of rubber in (I) is 2-20 pref. 5-15 wt.%. (II) is esp. poly(2,6-dimethyl-1,4-phenylene)ether (IIA). The mouldings have low shrinkage and high impact resistance.
