The present invention has for its object to provide a fluorocopolymer which is available at low cost, has fluidity at room temperature, and is curable, a method of producing the same copolymer and a curable composition having good processability and in situ moldability. The present invention is directed to a fluorocopolymer which is fluid at room temperature and curable, and which is obtainable from a trifluorovinyl group-containing monomer with an ethylenically unsaturated double bond moiety being a trifluorovinyl group.

Fluorocopolymer, process for producing fluorocopolymer, fluorocopolymer curable composition, and cured object

An ultraviolet-crosslinkable polymer composition comprising a polymer containing iodine and/or bromine in an amount of from 0.001 to 10% by weight, a photoinitiator as a crosslinking agent and a polyfunctional unsaturated compound as a crosslinking aid. By using iodine and/or bromine as a crosslinking point, it is possible to carry out crosslinking of various polymers including fluorine-containing polymers which have been very difficult to crosslink with ultraviolet rays, and molding or processing can be made easily at working site at low temperature.

Rubber compositions of low compression set

Crosslinkable composition

A fluororubber composition comprising 100 parts by weight of a rubber mixture which comprises 5 to 70% by weight of at least one rubber selected from the group consisting of diene rubbers and polyolefin rubbers and 95 to 30 by weight of a fluororubber and 1 to 20 parts by weight of a block copolymer which comprises a vinyl monomer and a fluorovinyl monomer, which has good compatibility between the rubber components and gives a cured material having improved chemical resistance, heat resistance, oil resistance, and the like.
