摘要： The present invention relates a hydroxyl-functionalized unimodal polysiloxane polyalkyleneglycol brush copolymer of the structure [A(-X—B)]s, wherein: A represents said polysiloxane backbone; B represents said polyalkyleneglycol side chain; X is a linker group characterized by including the moiety Si—C—C— of which said Si is a part of the polysiloxane backbone A; and s is an integer of from 1 to 100, wherein the polysiloxane backbone A contains less than 500 ppm mol % of SiH moiety based on the total moles of the silicon atom which constitutes the polysiloxane backbone, and said copolymer has a polydispersity index of from 1.3 to 5.0; and a method for producing said hydroxyl-functionalized unimodal polysiloxane polyalkyleneglycol brush copolymer.
