摘要：
A polymer having at least one urea linkage prepared by: (i) reacting (a) at least one diisocyanate, polyisocyanate, or mixture thereof, having isocyanate groups, and (b) at least one fluorinated compound selected from the formula (I): Rf(CH2CF2)p(CH2CH2)qR1)r—XH Formula (I) wherein p and q are each independently an integer of 1 to 3; r is 0 or 1; X is —O—, —NH— or —S—; R1 is a divalent radical selected from the group consisting of —S(CH2)n—, n is an integer of 2 to 4; s is an integer of 1 to 50; R2, R3, and R4 are each independently hydrogen or an alkyl group containing 1 to 6 carbon atoms; and Rf is a perfluoroalkyl group having 1 to 6 carbon atoms; and (i) reacting with (c) water, a linking agent, or a mixture thereof and methods for treating substrates therewith.
