FLUOROACRYLATE-MULTIFUNCTIONAL ACRYLATE COPOLYMER COMPOSITIONS

摘要

A composition comprises a copolymer comprising repeating units derived from at least one co-reactant comprising two or more acrylate groups and repeating units derived from a fluoroacrylate comprising the reaction product of: (a) at least one fluorochemical alcohol represented by the formula: C₄F₉-X-OH wherein: R=hydrogen or an alkyl group of 1 to 4 carbon atoms, m=2 to 8, R_f=C_nF_2n+1, n=1 to 5, y = 0 to 6, and q=1 to 8; (b) at least one unbranched symmetric diisocyanate; and (c) at least one hydroxy-terminated alkyl (meth)acrylate or 2-fluoroacrylate monomer having 2 to about 30 carbon atoms in its alkylene portion; wherein the composition is coatable.
