Polymers with primary amino groups their preparation and their use

摘要

Polymers that contain terminal amino groups and moieties of the formula (I) <IMAGE> a process for preparing the polymers by (a) reacting in a first step a hydroxyl-containing ester of an alpha , beta -olefinically unsaturated monocarboxylic or dicarboxylic acid and a dihydric alcohol with a diisocyanate, the equivalence ratio of NCO to OH groups being greater than 1:1, (b) polymerizing the reaction product of (a) alone or in mixture with at least one olefinically unsaturated polymerizable monomer by free-radical polymerization, (c) decarboxylating the polymer into the ammonium salt, and then neutralizing the resulting product and their use in 2-component finishes that crosslink by means of crosslinking agents.
