EPOXY-FUNCTIONALIZED PERFLUOROPOLYETHER POLYURETHANES

摘要

Disclosed are epoxy-functionalized perfluoropolyether polyurethane compounds having the following general structure (RfQX1C(O)NH)m-Ri-(NHC(O)X2Q(E)o)n wherein Rf is a monovalent perfluoropolyether moiety; Q is independently a connecting group of valence at least 2, which may contain heteroatoms; X1 is O, S, or NR, wherein R is H or a lower alkyl of 1 to 4 carbon atoms; Ri is a residue of a multi-isocyanate; X2 is O, S, or NR, wherein R is a lower alkyl of 1 to 4 carbon atoms; E is an organic group having at least one oxirane ring; m is at least 1; n is at least 1; o is 1, 2 or 3; and m + n is from 2 to 10.
