    Abstract: A method for the production of impact-resistant moulding materials by anionic polymerization of vinyl aromatic monomers in the presence of rubber in a continuously through-flown reactor cascade consisting of at least two reactors. The vinyl aromatic monomers are fed to the reactors of the reactor cascade in partial flows and an anionic initiator and rubber are fed to at least the first reactor. The reactor cascade consists of backmixed reactors.

    Abstract: Transparent, impact-resistant thermoplastic moulding materials containing (A) a methyl methacrylate (co)polymer, (B) a vinylaromatic-acrylonitrile copolymer and (C) a graft copolymer with a bimodal particle size distribution, in which the difference between the refractive index of (C) and that of the mixture of other components is less than 0.01. Transparent, impact-resistant thermoplastic moulding materials (I) containing a mixture of (A) 4-80 wt% methyl methacrylate (MMA) polymer derived from 90-100 wt% MMA and 0-10 wt% 1-8C alkyl acrylate, (B) 5-75 wt% of a copolymer of 78-88 wt% vinylaromatic monomer (VAr) and 12-22 wt% acrylonitrile (AN), (C) 10-91 wt% of a graft copolymer with a bimodal particle size distribution, comprising an elastomeric core with a glass transition point (Tg) below 0 deg C and one or more grafted shells based on 1-8C alkyl (meth)acrylate esters and optionally VAr (up to 22C) and/or crosslinking monomers and (D) 0-20 wt% additives, in which the amounts of (A), (B) and (C) add up to 100 wt% and the difference between the refractive index (RI) of component (C) and that of the mixture of (A), (B) and optionally (D) is less than 0.01 units. Independent claims are also included for (a) a method for the production of (I) by melt-compounding the components; (b) film, fibres and moulded products consisting essentially of (I).
