FLUORINATED ETHOXYLATED POLYURETHANES

摘要

The present invention comprises fluorinated ethoxylated polyurethanes of formula [Rf-(X)n-(CH2CHR1-O)m-CH2CH2-O-C(O)-NH]p-A, wherein Rf is a C1 to C6 perfluoroalkyl; X is a divalent radical; n is 0 or 1; R1 is H or C1 to C4 alkyl; m is 1 to 20; p is a positive integer of at least 2; and A is the residue of a polyisocyanate, and methods for altering surface behavior of liquids using such compounds.
