FLUORINATED POLYISOCYANATES

摘要

A fluorinated polyisocyanate which comprises an organic polyisocyanate reacted with a fluorinated monofunctional alcohol represented by formula (I), where Rf is a fluoroalkyl containing group having at least 4 carbon atoms, X is a divalent radical, R<3> is H or an alkyl group having 1-4 carbon atoms, n is 0-1 and m is 0-30, provided that when n is 0 then m must be equal to or greater than 1 and when m is 0, n is 1, wherein about 0.1-33 mole percent of active isocyanate groups are reacted with the fluorinated monofunctional alcohol; the fluorinated polyisocyanate can be used with acrylic polymers, polyesters, alkyl resins, polyols and the like to form coating compositions, sealants, adhesives and the like.
