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."LEATHER TREATMENT PROCESS, AMPHIFYLIC COPOLIMER, USE AND PROCESS OF OBTAINING THE SAME, LEATHER, AND, WATER COMPOSITION". The present invention provides an amphiphilic copolymer comprising repeating units (I) and (II) wherein: R ~ f ~ represents a fluorinated alkyl group having at least 3 carbonol atoms Q and Q 'each independently represents a group organic bonding or other chemical bonding; R ^ 1 ^ and R ^ 2 ^ each independently represents hydrogen or a C ~ 1 ~ to C ~ 4 ~ alkyl group; and R ~ h ~ represents a hydrocarbon group having at least 8 carbon atoms and optionally containing 1 to 3 substituents; and a repeating unit comprising at least one carboxylic acid group or salt thereof. The present invention also provides a process for obtaining the above amphiphilic copolymer. The amphiphilic copolymer can be used in a leather treatment to confer impermeability to the leather.
