Abstract

"POLIURETANO/URéIAS úTEIS PARA A PRODUçãO DE SPANDEX E PROCESSO PARA A PRODUçãO DAS MESMAS". São produzidas poliuretano/uréias segmentadas úteis para a produção de spandex através do prolongamento da cadeia de um pré-polímero terminado em isocianato com um prolongador de cadeia de diamina que inclui: (1) a partir de cerca de 7 até 25 por cento em equivalentes de uma diamina alifática e/ou cicloalifática assimétrica e (2) uma diamina linear tal como a etileno diamina na presença de um solvente. O pré-polímero terminado em isocianato é produzido através da reação de um excesso estequiométrico de um isocianato com um componente reativo ao isocianato que inclui: (1) a partir de cerca de 10 até cerca de 70 por cento em equivalentes de um polioxipropileno diol tendo um peso molecular em excesso de 1500 Da e um nível médio de não-saturação de não mais do que cerca de 0,03 meq/g e (2) a partir de cerca de 30 até cerca de 90 por cento em equivalentes de um politetrametileno éter glicol que tenha um peso molecular de pelo menos 600 Da.
