摘要： Hardeners are described for synthetic resins which contain groups which are capable of ester or amide formation and, if appropriate, polymerizable double bonds. The new hardeners, which allow lower crosslinking temperatures, are products (A) of the Michael addition of compounds (B), containing Michael addition-capable ester groups, to compounds (C) which contain at least two Michael addition-capable double bonds, the products (A) having an average of at least one polymerization-capable double bond and at least two transesterification- or transamidation-capable ester groups per molecule and the compound (B) representing products of the reaction of (b1) CH-active alkyl esters and (b2) polyisocyanates.

摘要： Polymers that contain terminal amino groups and moieties of the formula (I) ##STR1## 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.
