Методика

399 g of hexamethylene diisocyanate (HDI) were initially introduced at 80° C. in a 1 l round-bottomed flask and 0.002 g of isophthaloyl dichloride was added. 73.4 g of 2,2,3,3,4,4,5,5-octafluoropentanol were slowly added dropwise and stirring was effected until the NCO value was 39.4% by weight. The mixture was separated by distillation on a thin-film evaporator and 40 g (=40% of theory) of the title compound having an NCO content of 12.4% by weight were obtained.
