Abstract:
A water vapor-permeable, waterproof linear polyurethane-urea polymer consisting of at least four soft segments: polytetramethylene oxide, polyethyleneoxide and polycaprolactone-polydimethylsiloxane-polycaprolactone. The soft segments are linked together with a diisocyanate and chain extended with a diamine. The polymer is utilized to coat various textile materials. The compositions of the polymer as well as various methods of coating the textile materials are described.
Abstract:
A water vapor-permeable, waterproof adhesive polymer and a linear polyurethane-urea polymer, either alone or in combination with one another, are utilized to coat various textile materials. The compositions of these polymers as well as various methods of coating the textile materials are described.
