Patent ID: 8153722

Claim:
A curable polymer mixture comprising 1) at least one at least oligomeric addition product a) of at least one aminosilane and/or thiosilane having at least one hydrolysable silane group and at least one compound having at least two terminal, ethylenically unsaturated double bonds as the only terminal groups, and/or at least one at least oligomeric addition product b) of at least one isocyanate silane and/or epoxy silane having at least one hydrolysable silane group and at least one oligomeric compound having at least three structural units and at least one terminal hydroxyl group or terminal amino group and at least one terminal ethylenically unsaturated double bond as coupling additive, 2) a system which can be cured by radical polymerisation, comprising at least one ethylenically unsaturated polymer and/or a (meth)acrylic resin, at least one ethylenically unsaturated monomer, at least one radical initiator and optionally at least one cross-linking agent as binder system, 3) at least 20% by weight, based on the total weight of components 1) to 4) of the polymer mixture, of inorganic, optionally multiparticulate, fillers as aggregates, and 4) optionally conventional auxiliaries.
