Fluorine-containing diols and use thereof

摘要

Fluorine-containing diols represented by the following formula are provided:wherein Rf represents a perfluoroalkyl or perfluoroalkenyl group having 1 to 20 carbon atoms; X represents a substituted or unsubstituted alkylene group having 1 to 10 carbon atoms, a substituted or unsubstituted alkenylene group represented by -CH=CH-(CH2)n- in which n is from 1 to 10, orin which n is from 0 to 6; Y represents a direct bond, -O-, -NH-, or -R0-NH- in which R0 is an alkylene group having 1 to 6 carbon atoms; Z represents a direct bond or -N(R')R- in which R is an alkylene group having 1 to 20 carbon atoms and R' is a hydrogen atom or an alkyl group having 1 to 6 carbon atoms; R1 and R2 divalent organic groups; and R3 represents a residual group of diisocyanate. These diols are useful for polyurethanes.
