摘要

Poliuretanouru00e9ia, spandex, polyurethane, process for the preparation of spandex fabric, garment or article, textile, dispersion, coating, film, adhesive, elastu00c8mero or an article molded and method for the manufacture of spandex.The present invention relates to a composition of poliuretanouru00e9ia comprising poly (tetrametileno Co etiu00edenou00e9ter) glycol which has about 37 about 70% at Moi of content of etiu00edenou00e9ter and ethylenediamine as the extender.The present invention also relates to the use of high content of etilenou00e9ter of poly (tetrametileno Co etilenou00e9ter) glycol as the base material of soft segment compositions of spandex. The present invention also refers to new compositions of polyurethane comprising the poly (tetrametileno Co etilenou00e9ter) glycols with such high levels of etilenou00e9ter and its use in spandex.
