Abstract
A novel copolymer comprising PA0 (a) repeating units of the formula: EQU --OCH[(CH.sub.2).sub.p R.sub.f ]CH.sub.2 -- (Ia) PA0 or EQU --OCH.sub.2 CH[(CH.sub.2).sub.p R.sub.f ]-- (Ib) wherein R.sub.f is C.sub.3 -C.sub.21 perfluoroalkyl and p is an integer of 1 to 10 and PA0 (b) repeating units of the formula: EQU --(OCH.sub.2).sub.m (CH.sub.2).sub.n -- (II) wherein m is an integer of 1 to 4 and n is an integer of 2 to 10 when m is 1, an integer of 1 to 8 when m is 2 or an integer of 0 to (12-2m) when m is 3 or 4, EQU --OCH.sub.2 CR.sup.1 R.sup.2 CH.sub.2 -- (III) wherein R.sup.1 and R.sup.2 are each hydrogen, CH.sub.3, CH.sub.2 Cl, CH.sub.2 F, CH.sub.2 OCH.sub.3, CH.sub.2 OC.sub.2 H.sub.5, CH.sub.2 OCOCH.sub.3, CH.sub.2 OC.sub.6 H.sub.5, CH.sub.2 OH or CH.sub.2 CN provided that at least one of them is not hydrogen, EQU --OCH.sub.2 (OCH.sub.2 CH.sub.2).sub.q -- (IV) wherein q is 2 or 3, and/or EQU --[(R.sup.3).sub.r --COO]-- (V) wherein R.sup.3 is CH.sub.2 or CF.sub.2 and r is an integer of 2 to 5, which is particularly useful as a water- and oil-repellent and a non-tackifier.
