Abstract
Hydrophilic polyester resin is provided by the method comprising reacting an aromatic dicarboxylic acid or diester thereof, a diol and a polysiloxane-polyether copolymer wherein the polysiloxane backbone is endblocked with a hydroxyl-substituted organic group and the polyether portion of the copolymer comprises polyoxyethylene. The resulting silicone-modified polyester is especially suited for making hydrophilic fiber and film.
