SOIL RELEASE POLYMERS AND LAUNDRY DETERGENT COMPOSITIONS CONTAINING THEM

The invention provides a polymer providing soil release properties (also termed a "soil release polymer" or SRP) when incorporated in a laundry detergent composition, the polymer comprising a capped polyoxyalkylene end block connected to a polyester segment; the polyester segment comprising alternating -B1-A-B2- and -R- units; in which B1 and B2 are each independently selected from -OC(O)- and -C(O)O- groups; A is a 2,5-furanylene ring and R is a divalent alkylene radical. The polymer provides good compatibility, stability and cleaning performance when incorporated into a laundry detergent composition, preferably a liquid laundry detergent composition, comprising one or more detersive surfactants. 本发明提供了当引入到洗衣洗涤剂组合物中时提供去污性质的聚合物(也称为"去污聚合物"或SRP)，所述聚合物包含连接到聚酯链段的封端的聚氧亚烷基末端嵌段；所述聚酯链段包含交替的-B-A-B-和-R-单元；其中B和B各自独立地选自-OC(O)-和-C(O)O-基团；A为2,5-亚呋喃基环，且R为二价亚烷基基团。所述聚合物当引入到包含一种或多种洗涤表面活性剂的洗衣洗涤剂组合物，优选液体洗衣洗涤剂组合物中时提供良好的相容性、稳定性和清洁性能。
