Abstract

A fluorinated polyester blend is 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 blend is useful for preparing fibers, yarns, fabrics, garments, carpets, and other shaped articles. The shaped articles exhibit durable soil, oil, and water repellency.
