STRUCTURE-PROPERTY RELATIONSHIPS OF POLYACRYLATE RETANNING AGENTS

Retanning products that are based on acrylic acid have been known and used for several decades. Such agents have proliferated worldwide beca use they impart leather with specific value added performance not atta ined with older and/or newer products derived from other chemistries. The credibility and acceptance of the polyacrylate retans have spurred and led to the development of still newer products. This is an ongoin g and evolutionary process that is driven by the needs of the customer and cost. The purpose of this paper is to relate the key attributes o f the structure/composition of polyacrylates with the endowed leather properties.
