A process for preparing fluorochemical monoisocyanates comprises reacting at least one fluorochemical alcohol represented by the formula CnF2n+1SO2NCH3 (CH2) mOH, wherein n = 2 to 5, and m = 2 to 4, with 4,4' -diphenylmethane diisocyanate (MDI) in a solvent in which the resulting fluorochemical monoisocyanate is not soluble; wherein the molar ratio of fluorochemical alcohol:MDI is from about 1:1 to about 1:2.5.

Ce procédé pour préparer des monoisocyanates fluorés consiste à faire réagir au moins un alcool fluoré représenté par la formule C¿n?F¿2n+1?SO¿2?NCH¿3 ?(CH¿2?) ¿m?OH, dans laquelle n = 2 à 5, et m = 2 à 4, avec?¿du? ¿4,4'-diphénylméthane diisocyanate (MDI) dans un solvant dans lequel le monoisocyanate fluoré obtenu n'est pas soluble; la proportion molaire de l'alcool fluoré par rapport au MDI étant d'environ 1:1 à environ 1:2,5.?.¿
