摘要

(57) [Abstract] The present invention, adducts, compounds having a ethenyl arylene mono isocyanates, polyols, hydroxyl and amino groups and / or polyamine, a polyurethane prepolymer having free isocyanate groups which are not blocked can be prepared by reacting the adduct obtained by reacting isocyanate-reactive groups such that the remaining one at least during ethenyl arylene groups and / or terminal ethenyl arylene group of the side self-crosslinking polyurethane having a (B); containing and (B) at least one polyurethane and at least one (A) (meth) acrylate copolymers, blocked isocyanate groups and ethenyl arylene group of the terminal and / or lateral dispersed in an aqueous medium (B) at least one olefinically unsaturated polyurethane of self-crosslinking having, then copolymerized with the monomers (a1) and the monomer having having at least one functional group of the isocyanate-reactive self-crosslinking graft copolymer may be prepared by radical emulsion copolymerization in the presence of the monomer (B) can be a polyurethane and (a2); coating material self-crosslinking and, adhesives and producing a packing material regarding the use of self-crosslinking graft polymer / or self-crosslinking polyurethane to and (B).
