ABSTRACT:
A water soluble or water dispersible fluorochemical silane represented by the general formula (I):in-line-formulae description="In-line Formulae" end="lead"?X-MfnMhmMar-Gin-line-formulae description="In-line Formulae" end="tail"?wherein X represents the residue of an initiator or hydrogen; Mfrepresents units derived from one or more fluorinated monomer; Mhrepresents units derived from one or more non-fluorinated monomer; Marepresents units having a silyl group; G is a monovalent organic group comprising the residue of a chain transfer agent; n represents a value of 1 to 100; m represents a value of 0 to 100; and r represents a value of 0 to 100; and n+m+r is at least 2;with the proviso that at least one of the following conditions is fulfilled: (a) G contains a silyl group of the formula (III):wherein Y1, Y2and Y3each independently represents an alkyl group, an aryl group or a hydrolyzable group and at least one of Y1, Y2and Y3represents a hydrolyzable water solubilising group; or(b) r is at least 1 and at least one of Y4, Y5and Y6represents a hydrolyzable water solubilizing group.
