PURPOSE:To provide the titled composition having pressure-sensitive adhesivity and excellent processability, and giving a sheet having smooth surface, by adding a specific liquid polymer to the base resin. CONSTITUTION:100pts.(wt.) of a fluorine-containing elastomer is compounded with 1-50pts., preferably 3-30pts. of a liquid polymer having a weight-average molecular weight of 8,000-200,000 (reduced to polystyrene and calculated from a gelpermeation chromatogram). The elastomer is selected from tetrafluoroethylene-propylene copolymer, vinylidenne fluoride-hexafluoropropylene copolymer, and vinylidene fluoride-hexafluoropropylene-tetrafluoroethylene terpolymer. The liquid polymer is preferably polyisobutylene or polybutene. |
