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.
