FLUOROALKYLSILANES AND COATINGS THEREFROM

摘要

Novel fluoroalkysilanes of the following formula are described; Rf-O-CHFCF2-O-(CH2)n-Si(R)xX3-X, wherein Rf is a perfluoroaikyl group, optionally substituted by one or more in-chain -Q-, -S- or -NRf1 - hetcroatorns, where Rf 1 is a -perfluoroaikyl; X is a hydro! ysable group; R is a C1C4 aikyl group; n is at least 3; and x is 1 to 3.
