The present invention relates to novel polymer compositions, to a process for their manufacturing, to the use of said polymer compositions for modifying the viscosity of aqueous compositions, and to water-borne coating compositions containing the novel polymer compositions as thickeners. The polymer compositions comprise a polymer material which is obtainable by reacting: a) a polymer P1 having at least one functional group of the formula (I), where k is an integer from 0 to 4; n is 0 or 1 p is an integer from 1 to 10, the number average of p being from 1.5 to 10; Q is a divalent moiety selected from the group consisting of —O— and —NH—; P is a p-valent hydrophilic neutral polymer radical; and R1 is as defined in the claims; with b) a succinic anhydride of the formula (II) where R is C4-C24-alkyl or C4-C24-alkenyl.
本发明涉及新型聚合物组合物、其制造工艺、使用所述聚合物组合物调节水性组合物粘度的 方法,以及含有新型聚合物组合物作为增稠剂的水性涂料组合物。所述聚合物组合物包括一种聚合物材料,该聚合物材料可通过以下反应获得: a) 具有至少一个式(I)官能团的聚合物 P1,其中 k 是 0 至 4 的整数;n 是 0 或 1 p 是 1 至 10 的整数,p 的平均数为 1.5至10;Q是选自-O-和-NH-组成的组的二价分子;P是p价亲水性中性聚合物基团;R1如权利要求中所定义;b)式(II)的琥珀酸酐,其中R是C4-C24-烷基或C4-C24-烯基。
