    • Condensation products based on colophonium maleic imides are obtained by A) reaction of 100 parts by weight of colophonium with 1 to 20 parts by weight of maleic anhydride at a temperature between 150 and 250°C; B) reaction of the adduct (A) formed in step A with an amino alcohol containing a primary amine group at temperatrues of 130 to 250 °C, in a molar ratio of anhydride groups to amino groups of 0.8 to 1.2:1; C) if necessary, further condensation of the condensation product (B) at a temperature between 180 and 300°C and/or D) if necessary, further reaction of the condensation product (B) or (C) formed in step B or C with a dimeric and/or trimeric fatty acid at temperatures between 150 and 300°C, in a molar ratio of hydroxyl groups of the condensation product (B) or (C) to carboxylic groups of the fatty acid from 0.1 to 1.2:1 and E) reaction of the condensation product (B), (C) or (D) formed in step B, C or D with a polyalcohol of functionality 3 to 6 at temperatures between 230 and 300°C, in a molar ratio of carboxylic groups to hydroxyl groups of 0.7 to 1.5:1.
    • 所述产品通过以下步骤获得:(A)将100重量份的松香与1至20重量份的马来酸酐在150至250℃的温度下转化; (B)在130-250℃的温度下用伯氨基醇将相(A)中得到的加合物再转化,酸酐基和氨基之间的摩尔比在0 ,8和1.2为1; (C)适当时,在180-300℃的温度下缩合缩合产物(B); 和/或(D)如果合适的话,用二聚体和/或三聚体脂肪酸在阶段(B)或(C)期间获得的缩合产物(B)或 150℃和300℃,缩合产物(B)或(C)的羟基与脂肪酸的羧基之间的摩尔比为1至0.1至1.2; 和(E)将在阶段(B),(C)或(D)期间获得的缩合产物(B),(C)或(D)再转变成官能度为3-6 在230和300℃之间的温度下,羧基和羟基之间的摩尔比在1和0.7之间为1.5。
