(i) reacting (a) at least one diisocyanate, polyisocyanate, or mixture thereof, having an isocyanate group, and (b) at least one fluorinated compound selected from formula (I): (I) R f 1 -LX [here, R f 1 is a monovalent, partially or fully fluorinated, linear or branched, alkyl radical having 2 to about 100 carbon atoms; 1 to 50 oxygen atoms are optionally interrupted; Wherein the ratio of carbon atoms to oxygen atoms is at least 2: 1 and the oxygen atoms are not bonded to each other at all; L is a bond or a linear or branched divalent linking group having from 1 to 20 carbon atoms, said linking group being -O-, -NR-, -S-, -SO-, -SO 2- , -N Is optionally interrupted by 1 to 4 hetero-radicals selected from the group consisting of (R) C (O)-, wherein R is H or C 1 to C 6 alkyl, and the linking group is CH 2 Cl Optionally substituted; X is OH, -N (R) H, and SH, where R is H or C 1 To C 6 alkyl); an isocyanate-reactive group selected from the group consisting of C; Thereafter, the composition comprising a polymer prepared by reacting with (c) water and (d) isocyanate-reactive non-fluorinated particulate components. |
