Patent ID: 7129288

Claim:
A polymer mixture, based on polyurethane, comprising a reaction product of at least one olefinically unsaturated monomer with at least one polyurethane containing sulfide groups, the polyurethane comprising at least one of i) at least one group of general formula I in the polymer main chain, and ii) at least two terminal groups of general formula II: —X—A—S—B—Y— (I) —X—A—S—B—YH (II) wherein: S is a sulfur atom: X and Y independently of one another are oxygen atoms, sulfur atoms, or groups —NZ, wherein Z is a hydrogen atom or an alkyl radical of 1 to 10 carbon atoms; and A and B independently of one another are divalent organic radicals, wherein the reaction product is in a solution or in an aqueous dispersion.
