Abstract

"PROCESSO DE TRATAMENTO DE COURO, COPOLìMERO ANFIFìLICIO, USO E PROCESSO DE OBTENçãO DO MESMO, COURO, E, COMPOSIçãO AQUOSA". A presente invenção fornecer um copolímero anfifílico que compreende as unidades de repetição (I) e (II) em que: R~ f~ representa um grupo alquila fluorado que tem pelo menos 3 átomos de carbonol Q e Q' cada um independentemente representa um grupo orgânico de ligação ou outra ligaçãp química; R^ 1^ e R^ 2^ cada um independentemente representa hidrogênio ou um grupo C~ 1~ a C~ 4~ alquila; e R~ h~ representa um grupo hidrocarboneto que tem pelo menos 8 átomos de carbono e opcionalmente contendo 1 a 3 substituintes; e uma unidade de repetição que compreende pelo menos um grupo ácido carboxílico ou sal do mesmo. A presente invenção também fornece um processo para a obtenção do copolímero anfifílico acima. O copolímero anfifílico pode ser usado em um tratamento de couro para conferir impermeabilidade ao couro.
