Abstract

Patente de Invenção: <B>"POLIURETANO-URéIAS, FIBRAS DE POLIURETANO-URéIA E PROCESSO PARA A SUA PREPARAçãO"<D>. Descreve-se um processo para a preparação de poliuretano-uréias, de novas poliuretano-uréias, a um processo para a preparação de fibras de elastano a partir de poliuretano-uréias e às fibras de elastano obteníveis de acordo com processo. As poliuretano-uréias são constituídas a partir de um diisocianato alifático ou cicloalifático, de um diol polimérico, de uma diamina alifática ou cicloalifática e, eventualmente, de uma amina alifática secundária. As fibras de elastano reunem excelentes propriedades mecânicas com boa resistência à luz.
