Polymethacrylimide mit hoher Wärmeformbeständigkeit

摘要

Copolymers obtainable by (I) copolymerisation of a monomer mixture comprising (A) from 1 to 98 % by weight of a monomer of the formula I in which the variables have the following meaning: R<1> to R<6> are hydrogen, C1-C10-alkyl, C1-C10-alkoxy, where an oxygen atom may be inserted between two carbon atoms in each of the alkyl or alkoxy radicals having more than one carbon atom, C5-C8-cycloakyl, optionally substituted C6-C10-aryl, C6-C10-aryl-C1-C10-alkyl, C6-C10-aryloxy, cyano, halogen, -CO-O-R<7>, -O-CO-R<7> or -CO-NR<7>R<8>, where R<7> and R<8> are hydrogen, C1-C10-alkyl, C5-C8-cylcoalkyl, optionally substituted C6-C10-aryl or C6-C10-aryl-C1-C10-alkyl; p is 0, 1 or 2; Z is -CH2-, oxygen or sulphur; Y is oxygen or -N-R<9>, where R<9> is hydrogen, C1-C22-alkyl, C5-C12-cycloalkyl, optionally C6-C10-aryl or C6-C10-aryl-C1-C10-alkyl; (B)from 1 to 98 % by weight of a compound selected from the group consisting of acrylic and methacrylic acid and esters thereof, and (C) from 0 to 98 % by weight of a further monomer, and (II) reaction of the resultant copolymers with a primary amine, and a process for the preparation of these copolymers, their use for the production of mouldings, and mouldings made from these polymers, homopolymers and copolymers as intermediates.
