摘要：
A fluorochemical compound comprises the reaction product of: (a) the reaction product of: (i) at least one fluorochemical alcohol represented by the formula: CnF2n+1—X—OH wherein: n=1 to 6, R=hydrogen or an alkyl group of 1 to 4 carbon atoms, m=2 to 8, Rf=CnF2n+1, y=0 to 6, q=1 to 8; and (ii) at least one unbranched symmetric diisocyanate, and (b) at least one co-reactant comprising two or more functional groups that are capable of reacting with an isocyanate group.
