Abstract
A graft polymer of polyvinylidene fluoride wherein the polyvinylidene fluoride has grafted thereon a polymer of an ethylenically unsaturated compound and a process for preparing such graft polymer by contacting polyvinylidene fluoride with a monomer of an ethylenically unsaturated compound in the presence of a radical forming catalyst while the polyvinylidene fluoride is maintained in the solid phase under conditions for polymerization of the ethylenically unsaturated compound.
