A fluorine-containing copolymer comprising

Novel copolymer and water- and oil-repellent comprising the same

Disclosed is A water- and oil-repellent composition comprising (A) at least one species selected from the group consisting of a homopolymer and a copolymer of perfluoroalkyl group-containing acrylate, a homopolymer and a copolymer of methacrylate, a copolymer of the same and a monomer copolymerizable therewith and a perfluoroalkyl group-containing urethane compound, and (B) a ladder polymer of organosilsesquioxane.

Water- and oil-repellent composition

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

Mold release composition

A copolymer comprising 50 to 90% by weight of the constituting unit derived from (a) a polymerizable compound having a perfluoroalkyl group of 4 to 20 carbon atoms, 10 to 50% by weight of the constituting unit derived from (b) cyclohexyl or benzyl ester of acrylic acid or methacrylic acid and 0.1 to 10% by weight of the constituting unit derived from (c) at least one selected from the group consisting of polyethylene glycol diacrylate of the formula

Fluorine-containing copolymer and oil and water repellent composition

A deicing coating composition characterized in that the composition comprises a synthetic resin coating composition of the organic solvent type, at least one fluorine-containing compound selected from the group consisting of urethane, phosphate, phosphonic acid derivative, phosphinic acid derivative, polyether, polyester and polyvinyl compounds having a perfluoroalkyl group with 6 to 20 carbon atoms, and when required, an alkali metal compound of the formula

Deicing coating composition

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 mold release composition consisting essentially of:

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 composition in the form of a solution or dispersion which includes a perfluoroalkyl group-containing phosphoric acid ester of the formula

Mold release agent

An epoxy resin composition which comprises (1) an epoxy resin represented by the formula: ##STR1## wherein n is an integer of 4 to 18 and (2) at least one of an initial condensation product of amino resin, an initial condensation product of amide resin and an initial condensation product of phenol-formaldehyde, which can afford hardened products being improved in contamination-preventing property, particularly adhesion resistance at high temperatures.
