摘要： A process for polymerizing oxiranes, oxetanes, oxepanes, dioxolanes, trioxanes, and tetrahydrofurans to their respective polymers by contacting them with a selected metal compound is disclosed; and also a process for depolymerizing polytetrahydrofurans to monomeric tetrahydrofurans by contacting the polymer with a selected metal compound at a temperature of about 100.degree. C. to about 250.degree. C. The catalysts may be in solution or part of a heterogeneous solid, and selected organic compounds are used as accelerators in the polymerizations. The polymeric products, some of which are novel, may be used as polyether monomers for further polymerization, as by reaction with isocyanates to produce polyurethanes, and other useful polymers. Some of the polymeric products are relatively high in molecular weight and are suitable for direct use, for instance as spandex fibers.

摘要： Woven, knit, and non-woven fabrics, and garments and other textile goods fabricated therefrom, are prepared from yarns comprising fibers comprising a fluorinated polyester blend 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 goods so produced exhibit durable soil, oil, and water repellency.

摘要： New fluorinated ethers of aromatic acids and diesters are disclosed. These compositions can be applied to, e.g., fibers, yarns, carpets, garments, films, molded parts, paper and cardboard, stone, and tile to impart soil, water and oil resistance. By incorporating the fluorinated ethers of aromatic acids, or diesters thereof, into polymer backbones, more lasting soil, water and oil resistance, as well as improved flame retardance, can be achieved.

摘要： 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.
