Abstract

''PROCESSO PARA PREPARAR UMA COMPOSIçãO FLUOROQUìMICA, COMPOSIçãO FLUOROQUìMICA, USO DA MESMA, PROCESSO PARA TRATAMENTO DE UM SUBSTRATO, E, SUBSTRATO''. Um processo para preparar uma composição fluoroquímica compreendendo um poliuretano por reação de: (A) oligómero fluoroquímico de fórmula (I): M^ f^~ m~M~ n~-Q^ 1^-T^ 1^, em que: M^ f^~ m~M~ n~ representa um oligómero fluoroquímico compreendendo m unidades derivadas a partir de monómero fluorado e n unidades derivadas a partir de monómero isento de flúor e em que os monómeros fluorados e os monómeros isentos de flúor podem ser os mesmos ou diferentes; m representa um valor de 2 a 40; n representa um valor de 0 a 20; T^ 1^ é -OH ou -NH~ 2~; Q^ 1^ e T^ 1^ representam conjuntamente o resíduo orgânico obtido pela remoção de um átomo de hidrogênio a partir de um agente de transferência de cadeia que é funcionalizado com T^ 1^; (B) composto difuncional capaz de reagir com um isocianato; (C) composto monofuncional capaz de reagir com um isocianato e compreendendo um grupo poli(oxialquileno) com (D) triisocianato. Substratos tratados com composições fluoroquímicas preparadas de acordo com o processo possuem boas propriedades de liberação de mancha, particularmente para manchas oleosas e manchas à base de água, tais que de vinho, chá e café.
