    Abstract: A process for making a solution of perfluorosulfonated ion exchange polymer is disclosed. The process involves heating a slurry containing a perfluorosulfonated ion exchange polymer resin, an organic ether compound and water in a mechanically agitated pressurized vessel to an elevated temperature, so as to totally dissolve the resin in the solution. The perfluorosulfonated ion exchange polymer solution is recovered, and the water and the organic ether compound are removed from the solution. A perfluorosulfonated ion exchange polymer resin remains, which can be coated onto a fabric, or converted into a film which can be laminated onto a fabric. The resulting fabric forms the basis for a chemical and/or biological agent barrier for use in certain types of apparel.

    Abstract: The present invention provides an improved process and apparatus for alkanolysis of polytetramethylene ether diacetate to polytetraalkylene ether glycol in the presence of a C1 to C4 alkanol and an alkali or alkaline earth metal catalyst wherein the catalyst component of the product mixture comprising polytetraalkylene ether glycol, alkanol and catalyst, essentially free of the alkanol acetate by-product, e.g., methyl acetate is removed by contacting the mixture in the absence of added water with certain ion exchange resin at specified contact conditions. The invention further provides a highly efficient method for removing the catalyst component of a mixture comprising polytetraalkylene ether glycol, alkanol and alkali or alkaline earth metal catalyst by contacting the mixture in the absence of added water with certain ion exchange resin at specified contact conditions,

    Abstract: The present invention relates to a new thermoplastic copolyether ester elastomer composition comprising a soft segment and a hard segment. The soft segment of the copolyether ester elastomer composition is derived from a random poly(oxyethylene-co-oxytetramethylene ether) glycol and the hard segment is composed of short chain polyester. The present invention also relates to a method for manufacturing the new copolyether ester elastomer composition, and products comprising same.
