  • Patent number: 8455592
    Abstract: Disclosed is a polycondensation process for preparing block copolyesters comprising blocks of fluoroether functionalized aromatic polyester and blocks of unmodified polyester. According to the process, a non-fluorinated poly(alkylene arylate) first homopolymer and a fluoroether functionalized poly(alkylene arylate) second homopolymer are combined to form a reaction mixture; the reaction mixture is heated to a temperature above the melting temperatures of each said homopolymer to prepare a molten reaction mixture; and the reaction is continued until the desired molecular weight is achieved. The block copolymers incorporated into blends with unmodified aromatic polyester impart oil and soil resistance to shaped articles prepared from the blends.
