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 &#x2014;B-A-B&#x2014; and &#x2014;R&#x2014; units; in which Band Bare each independently selected from &#x2014;OC(O)&#x2014; and &#x2014;C(O)O&#x2014; 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.
