Aqueous dispersion of copolymer for leather treatment

摘要

An aqueous dispersion of a copolymer having a weight average molecular weight of from 2,000 to 100,000, and formed from greater than 10% by weight to less than 50% by weight of acrylic acid or methacrylic acid monomer and from more than 50% by weight and less than 90% by weight of at least one of the following hydrophobic monomers: C10-22 alkyl (meth)acrylates, C8-22 alkoxy- or C6-12 alkyl phenoxy- poly (ethylene oxide)(meth)acrylates, C12-22 primary alkenes, and vinyl esters of C12-22 alkyl carboxylic acids is useful in a process for treating leather.
