A process for imparting releasing property to a mold which comprises applying to the mold a composition comprising:

Mold release composition

A fluorine-containing urethane compounds represented by the formula ##STR1## wherein R.sub.f represents a perfluoroalkyl group having 4 to 20 carbon atoms; X represents --CH.sub.2 CH(A)--, --C.sub.k H.sub.2k -- or --SO.sub.2 N(R.sup.3)C.sub.t H.sub.2t -- (in which A represents a methyl group or ethyl group; k and t are an integer of 1 to 4; and R.sup.3 is hydrogen atom or a lower alkyl group); R.sup.1 represents a n-valent organic group; R.sup.2 represents an alkyl group having 1 to 5 carbon atoms; n is an integer of 2 to 10; and m is an integer in the range of n.gtoreq.m.gtoreq.1, subject to the limitation that when n is 2, m is 2 and R.sup.1 is ##STR2## (in which Y is a divalent organic group) and a water and oil-repelling agent and a non-sticking agent containing the compound as the active ingredient.

Fluorine containing urethane compounds

A perfluoroalkylvinyl copolymer comprising (a) repeating units of the formula:

Perfluoroalkylvinyl polymer and production and use thereof

Omega-perfluoroalkyl-1,2-epoxyalkane copolymer and use thereof

A composition for preventing the adhesion of an epoxy resin which comprises a polymer of (A) at least one C.sub.4 to C.sub.21 perfluoroalkyl group-containing polymerizable compound with or without at least one compound copolymerizable therewith, the content of the component (A) being not less than 40% by weight on the weight of the polymer.

Prevention of adhesion of epoxy resins

A water and oil repellent essentially consisting of a copolymer comprising units of (a) at least one of fluoroalkyl group-containing polymerizable compounds and of (b) at least one of 2-hydroxy-3-chloropropyl acrylate and methacrylate of the formula:
