The nonaqueous polymer preparations essentially contain
A) 100 parts by weight of at least one finely divided polymer built up from
a) from 30 to 100 % by weight of methyl methacrylate (monomer I),
b) from 0 to 70 % by weight of an acrylate of a C1- to C8-alkanol or a methacrylate of a C2- to C8-alkanol or a mixture of these monomers (monomers II),
c) from 0 to 15 % by weight of an alpha , beta -monoethylenically unsaturated mono- and/or dicarboxylic acid containing 3 to 5 carbon atoms (monomers III),
d) from 0 to 20 % by weight of copolymerisable monomers containing at least one nitrogen-basic group and/or at least one hydroxyl group (monomers IV) and
e) from 0 to 5 % by weight of other copolymerisable monomers (monomers V), in polymerised form,
B) from 30 to 300 parts by weight of at least one polymer built up from
a) from 5 to 100 % by weight of glycidyl acrylate and/or methacrylate (monomers VI),
b) from 0 to 95 % by weight of an acrylate or methacrylate of a C1- to C8-alkanol or of a mixture of these monomers (monomers VII) and
c) from 0 to 30 % by weight of other copolymerisable monomers (monomers VIII), in polymerised form,
C) from 0 to 300 parts by weight of one or more inert fillers and
D) from 0 to 50 parts by weight of one or more adhesion promoters.
