    • The present invention relates to a process for the production of oxidatively crosslinkable, water-dilutable binders bya) forming a copolymer having intramolecular carboxylic anhydride groups by copolymerizing anhydride-functional compounds, other olefinically unsaturated monomers and 5 to 50% by weight, based on the weight of the olefinically unsaturated monomers used for the production of the copolymers a), of monomers which cannot be homopolymerized under the reaction conditions,b) subsequently reacting by ring-opening esterification at least 50% of the anhydride groups present in the copolymer with one or more unsaturated monohydric alcohols,c) reacting by ring-opening esterification up to 50% of the anhydride groups with monohydric saturated alcohols having a molecular weight of 32 to 200 either before, during or after step b),d) optionally reacting 1 to 70% of the carboxyl groups formed in steps b) and c) with organic epoxide compounds ande) neutralizing at least a portion of the carboxyl groups formed in steps b) and c).The present invention also relates to the binders obtained by this process and to their use in water-dilutable lacquers and coating compositions.
    • 本发明涉及通过以下方式制备可氧化交联的水可稀释粘合剂的方法:a)通过以下方式形成具有分子内羧酸酐基团的共聚物:通过将酐官能化合物,其它烯属不饱和单体和5-50重量% 用于生产共聚物a)的烯属不饱和单体的重量,在反应条件下不能均聚的单体,b)随后通过开环酯化反应使共聚物中存在的至少50%的酸酐基团与 一种或多种不饱和一元醇,c)在步骤b)之前,期间或之后,通过开环酯化至多50%酸酐基与分子量为32至200的一元饱和醇反应,d)任选地使1 至70%的步骤b)和c)中形成的羧基与有机环氧化合物反应,e)中和至少一部分 在步骤b)和c)中形成的羧基。 本发明还涉及通过该方法获得的粘合剂及其在水可稀释漆和涂料组合物中的用途。
