  • Thermoplastic moulding compounds exhibiting improved chemical resistance
    Publication number: 20070167573
    Abstract: The present invention relates to thermoplastic molding compositions comprising a mixture of (A) from 30 to 69% by weight, based on the sum of components (A), (B) and (C), of a methyl methacrylate polymer, (B) from 30 to 69% by weight, based on the sum of components (A), (B) and (C), of a copolymer obtainable by polymerizing a styrenic monomer and a vinyl cyanide, and (C) from 1 to 40% by weight, based on the sum of components (A), (B) and (C), of a graft copolymer obtainable from (C1) from 60 to 90% by weight, based on (C), of a core obtainable by polymerizing a 1,3-diene and a styrenic monomer, (C2) from 5 to 20% by weight, based on (C), of a first graft shell, and (C3) from 5 to 20% by weight, based on (C), of a second graft shell composed of an alkyl (meth)acrylate polymer, with the proviso that the ratio of (C2) to (C3) is in the range from 2:1 to 1:2, the essence of the invention being that the first graft shell (C2) is obtainable by polymerizing a monomer mixture consisting of (C21) from 30 to 39% by we

  • Method for preparing (co) polymers by metal-free anionic polymerization in the presence of a phosphonium cation containing at least one annellated aromatic ring
    Patent number: 6143847
    Abstract: The present invention concerns a novel method for preparing polymers (preferably (meth)acrylate polymers and copolymers) having a narrow molecular weight distribution by metal-free anionic polymerization in the presence of a phosphonium cation containing at least one annellated aromatic ring as substituent on the phosphorous atom.

  • Preparation of polyacrylates
    Patent number: 5830961
    Abstract: Polyacrylates based on alkyl acrylates or alkyl alkylacrylates or mixtures thereof as monomers are prepared in the presence of an initiator composition containing an alkali metal ester enolate and an organic aluminum compound or a mixture thereof, by a process in which an ester which differs from the monomers is present in the initiator composition, the carbon atom .alpha. to the ester group having no acidic proton.
