Résumé :	Acrylic resins are extensively used as retanning products because of their affinity with chrome tanned leather. However, their anionicity changes the cationic leather surface becoming a problem for the subsequent uses of fatliquoring and dyeing agents. As a result of changing charges, a leather with lower color intensity and poorer structural properties is obtained. This paper presents an initial study which analyses the use of polyacrylates esters based polycarboxylates (PCE) superplasticizers as a new retaining agent compared to traditional wet end acrylic resins. Properties of PCEs in leather were compared to acrylic resins. For the applying assays, PCEs with different molecular weight were synthetized and characterized using a gel permeation chromatography (GPC). Experimental results indicate that PCEs improve leather properties avoiding the dyeing and fatliquoring problems of the acrylic resins.
