Transparente Formmassen aus glutarimidhaltigen Polymeren und Styrol-Acrylnitril-Copolymeren

摘要

Transparent moulding compounds containing A) 1 to 99 wt % of a copolymer obtainable by polymerizing a mixture of monomers of a1) 50 to 90 wt % of a vinyl aromatic monomer, a2) 10 to 50 wt % acrylonitrile or methacrylonitrile or a mixture thereof, and a3) 0 to 30 wt % of another monomer, and B) 99 to 1 wt % of a polymer based on a vinyl aromatic monomer obtainable by 1) polymerizing a monomer mixture of b1) 60 to 99 wt % of a mixture consisting of b11) 100 to 50 wt % of a vinyl aromatic monomer and b12) 0 to 50 wt % acrylonitrile or methacrylonitrile or a mixture thereof, and b2) 40 to 1 wt % of a C1-C20 alkyl ester of methacrylic or acrylic acid or mixtures of such esters and 2) causing the polymers obtained according to 1) to react with an amine of the general formula (I): RNH2, in which R is C2-C10 alkyl, C5-C8 cycloalkyl, C6-C10 aryl or C6-C10-aryl-C1-C4 alkyl, where these radicals, except for the C2-C10 alkyl radical, can be substituted up to three times by radicals selected from the group consisting of C1-C4 alkyl, C1-C4 alkoxy and halogen.
