Abstract
A fluorohydrocarbon resin that has elasticity and retains favorable properties of known fluorohydrocarbon polymers is obtained by graft copolymerization of a fluorine-containing elastomeric polymer with a fluorine-containing crystalline polymer. One of the elastomeric and crystalline polymers is prepared by copolymerizing at least one fluorine-containing monomer with at least one unsaturated monomer that has peroxy bond. When the elastomeric polymer is employed as the basic polymer and the crystalline polymer is polyvinylidene fluoride, the graft copolymerized fluorohydrocarbon resin is high in mutual solubility with polyvinylidene fluoride, so that the addition of this resin to polyvinylidene fluoride gives a resin composition which has elasticity and good low temperature characteristics.
