Prepolymer catalysts suitable for preparing spandex fibers |
| abstract |
Segmented polyurethane / urea useful for the production of spandex, in particular spandex fibers, from isocyanate terminated prepolymers prepared by reacting excess isocyanate with an isocyanate-reactive component that meets specific compositional requirements in the presence of a catalyst that promotes linear polymerization but does not degrade the polymer. To prepare. Suitable catalysts include metal salts of organic fatty acids and / or naphthenic acid. Isocyanate-reactive components include polyoxypropylene diols having a number average molecular weight of at least 10 equivalents of at least about 1500 Da and an average unsaturation of at most 0.03 meq / g and polytetramethylene glycols having a number average molecular weight of at least 200 Da of at most 90 equivalents. |
