    Abstract: Copolymers obtainable by (1) copolymerisation of a monomer mixture of (A) from 1 to 99% by weight of at least one monomer of the formula I CH2 = C(E)CH2-O-CH2C(F) = CH2 I in which E and F are selected from the group consisting of -COOR , -COR , -CONR R and -CN, and R , R and R are defined as follows: R = H, C1-C18-alkyl, optionally substituted C3-C8-cycloalkyl or C3-C8-cycloalkyl-C1-C5-alkyl, hydroxy-C1-C5-alkyl, amino-C1-C 5-alkyl, N-C1-C4-alkylamino-C1-C5-alkyl, N,N-di(C1-C4-alkyl)amino-C1-C 5-alkyl, or optionally substituted C6-C18-aryl or C6-C18-aryl-C1-C4-alkyl; R and R = H, C1-C18-alkyl, optionally substituted C3-C8-cycloalkyl or C3-C8-cycloalkyl-C1-C5-alkyl, or optionally substituted C6-C18-aryl or C6-C18-aryl-C1-C4-alkyl; (B) from 99 to 1% by weight of at least one compound selected from the group consisting of acrylic and methacrylic acid and C1-C20-alkyl and C5-C12-cycloalkyl esters of acrylic and methacrylic acid, and (C) from 0 to 98% by weight of at least one further free-radical-polymerisable monomer, and (2) reaction of these copolymers with a compound of the formula II R NH2 II in which R is hydrogen, C1-C22-alkyl, C5-C8-cycloalkyl, C6-C10- aryl or C6-C10-aryl-C1-C4-alkyl, where these radicals, with the exception of hydrogen and the C1-C22-alkyl radicals, may be substituted, or mixtures thereof, and a process for the preparation of these copolymers, their use for the production of mouldings, films or fibres, and mouldings, films or fibres made from these polymers.
