Block polyesters having branched hydrophilic capping groups which are useful as soil release agents in detergent compositions are disclosed. Preferred polyesters have the formula:
wherein each R' is a 1,4-phenylene moiety; the R2 are essentially ethylene moieties, 1,2 propylene moieties or a mixture thereof; each X is ethyl or preferably methyl; each n, is from 1 to about 5; the sum of each n, + n2 is from about 12 to about 43; u is from about 3 to about 10.
本发明公开了具有支化亲水封端基团的嵌段聚酯,可用作洗涤剂组合物中的土壤释放剂。 优选的聚酯具有以下式子:其中每个 R' 是 1,4-亚苯基分子;R2 基本上是乙烯分子、1,2-丙烯分子或它们的混合物;每个 X 是乙基或最好是甲基;每个 n,从 1 到约 5;每个 n,+n2 的总和从约 12 到约 43;u 从约 3 到约 10。
