Abstract: The invention is directed to a process for preparing polyamide polymers, particularly nylon 6, 6 and nylon 6, comprising fluoroether functionalized aromatic repeat units. In one embodiment, 1,6 diaminohexane, adipic acid, and fluoroether functionalized terephthallic or isophthallic acid or diester are reacted to form a polymer. The polymers so formed are useful for imparting soil resistance to polyamides, particularly in the form of films, molded parts, fibers, fabrics, and carpets.

Suitable block copolyesters have a blockiness index, B, in the range of 0.25 to 1.0. Shaped articles that can be made from the copolyesters include films, fibers, and molded parts.

Abstract: Yarns comprising fibers comprising a fluorinated polyester blend are prepared by melt blending a fluorovinyl ether functionalized polyester with a non-fluorinated polyester. The fluoroether functionalized polyester can be a homopolymer or a copolymer. The yarns and fibers, and the textile and carpet goods produced therefrom, exhibit durable soil, oil, and water repellency.

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.
