Abstract
A perfluoroalkylvinyl copolymer comprising (a) repeating units of the formula: EQU --CHRfCH.sub.2 -- (I) wherein Rf is a C.sub.5 -C.sub.21 perfluoroalkyl group, and (b) repeating units of the formula: ##STR1## wherein Y is --OR.sup.1, --OCOR.sup.1 or --COOR.sup.1 and Z is a hydrogen atom or --COOR.sup.2 in which R.sup.1 and R.sup.2 are, the same or different, a C.sub.1 -C.sub.18 alkyl group with the proviso that when Y is --OR.sup.1 or --OCOR.sup.1, Z is an hydrogen atom, and R is a C.sub.1 -C.sub.18 alkyl group, which is useful as a mold release agent, a water- and oil-repellent and a non-tackifier.
