ABSTRACT:
An excellent fat-liquoring composition for leather comprises 100 parts by weight of a neutralized polybutene sulfonation product, 1-100 parts by weight of a polybutene and 1-100 parts by weight of one or more fatty acid salts. The polybutene employed herein has a number average molecular weight of 250-1500, is normally in a liquid form, and is obtained by polymerizing a mixed C.sub.4 fraction in the presence of a Friedel-Crafts type catalyst. The polybutene thus prepared is sulfonated with sulfur trioxide or chlorosulfonic acid with or without a diluent such as air, nitrogen, carbon dioxide or sulfur dioxide and liquid solvents, etc. to obtain a polybutene sulfonation product. The polybutene sulfonation product is neutralized with an aqueous solution of alkali metal hydroxides or ammonia to prepare neutralized polybutene sulfonation products. As fatty acid salt or salts, alkenylsuccinic acid salts having 12-28 carbon atoms, stearic acid salts, oleic acid salts, cetoleic acid salts, wool wax acid salts and others are effectively used. All these fatty acid salts have 12-28 carbon atoms.
