Verwendung von Pfropfpolymeren zum Fetten und Füllen von Leder und Pelzfellen

摘要

The invention relates to the use of water-soluble or dispersible graft polymers of vegetable and animal oils, obtainable by the radically initiated polymerisation A) of a monomer or monomer mixture of (a) 20 to 100 wt % monoethylenically unsaturated carboxylic acids and/or monoethylenically unsaturated sulphonic acids and/or monoethylenically unsaturated phosphonic acids or their alkaline, alkaline earth or ammonium salts, (b) 0 to 80 wt % other monoethylenically unsaturated monomers which can be copolymerised with monomers (a), and (c) 0 to 5 wt % at least double-ethylenic unconjugated unsaturated monomers, in the presence of B) vegetable and/or animal oils, in the weight ratio of A:B of (80 to 1):(20 to 99) to stuff and full leathers and fur pelts. This provides soft leathers with a pleasant feel.
