POLYMER FOR LEATHER TREATMENT AND LEATHER TREATMENT AGENT

摘要

A polymer for leather treatment and a leather treatment agent having excellent properties can be obtained from a fluorine-containing polymer comprising repeating units derived from: (A) a monomer which comprises; (a) a fluorine-containing monomer of the formula: CH2=C(X)COOYRf, wherein X is a hydrogen atom, a monovalent organic group, or a halogen atom, Y is a direct bond or a divalent organic group, and Rf is a fluoroalkyl group having 1 to 21 carbon atoms, wherein the monomer is polymerized in the presence of: (B) a mercapto functional organopolysiloxane.
