    Abstract: Compsns. (I) comprise (A) 50-90% (all pts.wt.) at least one aromatic polycarbonate; (B) 3-25% at least one polyphenylene ether; (C) 3-25% at least one graft polymer comprising (C1) 40-80 % graft core of rubber-eleastic polymer with Tg below 10 deg. C (C2) 20-60% graft shell comprising (C2.1) 50-95% opt. substd. styrene of formula (1) (where R1 is 1-8C alkyl or H; R2 is 1-8C alkyl; and n is 0-3) and/or Me (meth)acrylate (C2.2) 5-50% (meth)acrylonitrile, Me (meth)acrylate, maleic anhydride, and/or N-(1-8C alkyl)- or N-(6-20C aryl)-maleimide; (D) 3-40% thermoplastic copolymer of (D1) 50-95% at least one styrene of formula (1) (D2) 5-50% (meth)acrylonitrile, Me (meth)acrylate, maleic anhydride, and/or N-(1-8C alkyl)- or N-(6-20C aryl)-maleimide; and (E) 1-20% at least one vinyl aromatic polymer. Opt. (I) also contain (F) up to 20% at least one P cpd. of formula (2) (where R3, R4, R5 are halogen-free 1-8C alkyl or halogen-free 6-20C aryl opt. substd. by 1 or 2 (1-4C) alkyl; (G) up to 2% tetrafluoroethylene polymer; (H) up to 25% rubber different from (C). USE/ADVANTAGE - Prepn. of fibres, films, and shaped articles (claimed) for use in e.g., motor car mfr., building, office machines, and electrical and household appts., partic. by extrusion, injection moulding, calendering, blow moulding, pressing, or sintering. (I) have balanced property profile, partic. increased heat-dimensional stability.

    Abstract: Moulding material comprises (A) 5-95 wt.% graft copolymer comprising at least 1 wt.% of a core with a glass transition temp. (Tg) of more than 25 deg. C. at least 1 wt.% of a first layer of cross-linked polysiloxane of 5-95 wt.% of a second layer with a Tg greater than 25 deg. C of 50-100 wt.% vinyl aromatic monomer.; upto 10 wt.% polyfunctional cross-linking monomer and/or a graftable monomer with at least 2 functional gps. of different reactivity and upto 50 wt.% of one or more copolymerisable monomers and 1-100 wt.% (based on the sum of A1, A2 and A3) of a third layer comprising a copolymer of 1-99 wt.% aromatic monomer and 1-99 wt.% copolymerisable monomer and (B) 5-95 wt.% particulate graft copolymer of 30-80 wt.% of at least one elastomeric polymer with an average particle size of 20-1000 nm of 85-99.8 wt.% of at least one alkyl acrylate with 1-8C alkyl; 0.1-5 wt.% of at least one polyfunctional cross-linking monomer and 0.1-10 wt.% hydroxyalkylacrylate or methacrylate as graft base and 20-70 wt.% of a layer grafted onto (B1) comprising 50-90 wt.% of at least one vinyl aromatic monomer and 10-50 wt.% of at least one polar, copolymerisable alkene unsatd. monomer. (A) has an average particle size of 80-1500 nm. USE/ADVANTAGE - Material is useful for window frames, garden furniture, boats, signs, lampcovers, automobile parts and children's toys. Material exhibits high degree of toughness and has good resistance to weathering and ageing.
