Abstract:
A fluorine-containing adhesive comprising a fluorine-containing ethylenic polymer (A) having a functional group, said fluorine-containing ethylenic polymer (A) having a crystalline melting point of glass transition temperature of not more then 270Â° C. and is prepared by copolymerizing:(a) 0.05 to 30% by mole of at least one of fluorine-containing ethylenic monomers having at least one functional group selected from the group consisting of carboxyl and a carboxylic salt group, and (b) 70 to 99.95% by mole of at least one of fluorine-containing ethylenic monomers which do not have said functional group and is copolymerizable with said component (a), wherein the fluorine-containing ethylenic monomer (b) which does not have said functional group is a monomer mixture of 40 to 80% by mole of tetrafluoroethylene or chlorotrifluoroethylene, 20 to 60% by mole of ethylene and 0 to 15% by mole of a monomer copolymerizable with those monomers, a monomer mixture comprising 70 to 99% by mole of vinylidene fluoride and 1 to 30% by mole of tetrafluoroethylene, a monomer mixture comprising 50 to 99% by mole of vinylidene fluoride, 0 to 30% by mole of tetrafluoroethylene and 1 to 20% by mole of chlorotrifluoroethylene, a monomer mixture comprising 60 to 99% by mole of vinylidene fluoride, 0 to 30% by mole of tetrafluoroethylene and 1 to 10% by mole of hexafluoropropylene, or vinylidene fluoride.
