A presente invenção fornece um processo para preparar uma composição fluoroquímica compreendendo um uretano por reação de: (A) oligómero fluoroquímico da 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 um monómero fluorado e n unidades derivadas a partir de um monómero isento de flúor e em que os monómeros fluorados e os monómeros isentos de flúor podem ser o mesmo ou diferentes; m é um valor de cerca de 2 a 40; n é um valor de cerca de 0 a 20; T^ 1^ é uma porção -OH ou -NH~ 2~; Q^ 1^ e T^ 1^ representam conjuntamente um 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 monofuncional capaz de reagir com um isocianato e compreendendo um grupo poli(oxialquileno); (C) agente de bloqueio de isocianato ou oligómero isento de flúor, e (D) composto reativo a isocianato outro que o referido oligómero fluoroquímico, o referido agente de bloqueio de isocianato, o referido oligómero isento de flúor e o referido composto monofuncional; com (E) diisocianato ou um triisocianato, em que 33% a 67% do número de grupos isocianato são reagidos com o oligómero fluoroquímico de acordo com a fórmula (I), 33% a 67% do número de grupos isocianato são reagidos com o referido composto monofuncional, 0 a 33% do número de grupos isocianato são reagidos com um agente de bloqueio de isocianato ou um oligómero isento de flúor e de 0 a 10% do número de grupos isocianato são reagidos com o referido composto reativo a isocianato. Substratos tratados com a composição fluoroquímica produzidos de acordo com o processo acima descrito possuem boas propriedades de liberação de mancha, particularmente para manchas oleosas e manchas à base de água, tais que vinho, chá e café.
