Abstract
The invention relates to silicon compounds having formula (I):(RfCH2CH2)2-n[R(OCH2CHR′)mOR″]nSiX2 (I).In formula (I), Rf is a linear or branched perfluorinated hydrocarbon having 4 or more carbon atoms, R is a methyl or ethyl group, R′ is H or CH3, m is an integer of 1 to about 24, R″ is a hydrocarbon bridge having 1 to about 11 carbon atoms, n is an integer from 0 to 2, and X is H, Cl or an alkoxy group. The inventive materials may be used to produce siloxanes or silicones by hydrolytic condensation and have utility in surface modification.
