FLUOROCHEMICAL COMPOSITION AND USE THEREOF

摘要

The instant invention relates to the Fluorochemical composition comprising a dispersion or a solution of a fluorinated compound, wherein said fluorinated compound comprises the reaction product of at least two reactants A and B wherein reactant A being a compound of formula (I);
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ R f -O-(CF(CF 3 )CF 2 O) m CF(CF 3 )-X-Y-Z€ƒ€ƒ€ƒ€ƒ€ƒ(I)
with
R f
being a perfluorinated alkyl group,
m
being from 3 to25;
X
being a carbonyl group or CH2;
Y
being a chemical bond or an organic divalent or trivalent linking group bearing a functional or difunctional isocyanate reactive group;
Z
being an organic group bearing at least one cationic group,
reactant B being a polyfunctional isocyanate or a mixture thereof and optionally one or more isocyanate-reactive co-reactants C.
