摘要：
A hydroxypolyfluoroalkyl-containing silane derivative having the formula ##EQU1## WHEREIN EACH OF R.sup.1 and R.sup.3 is alkyl; each of R.sup.2 and R.sup.4 is alkylene; X is alkoxyl, alkyl, hydroxy, chlorine or hydrogen and at least one of the groups represented by X is alkoxyl, hydroxy, chlorine or hydrogen; p is 0 to 2, q is 0 or 1, r is 0 to 5, y is 1 or 2 and x is 2 or 3, provided that the sum of p and qr is at least 1 and the sum of x and y is 4; z is 1 or 2 and is equal to or less than y; and Z is a group represented by ##EQU2## WHEREIN R.sup.1, R.sup.2, R.sup.3, R.sup.4, p, q and r are the same as above and each of R.sup.5 and R.sup.6 is a hydrogen or ##EQU3## and at least one of the groups represented by R.sup.5 and R.sup.6 is ##EQU4## R.sub.f being a perfluoroalkyl group: the above compound being useful as water- and oil-repellent agent.
