Urethane reactions of cycloaliphatic and aromatic diisocyanates with hydroxy-terminated fluoropolyethers (FPEs) of various molecular weights and structure, at NCO : OH ฯญ 2, have been studied by monitoring, by IR analysis, the rate of decrease in NCO absorbance at 2264 -2268 cm ฯช1 . Different diisocy
