Abstract:
     In a gas phase graft polymerization method wherein at least one radical polymerizable monomer is graft-polymerized onto a polymer by feeding the monomer in the gaseous state onto the polymer while maintaining the polymer substantially in the solid state, an improvement wherein a radical polymerization initiator is fed in the gaseous state onto the polymer. According to the process, the polymer is impregnated with the initiator in the dry state without using a solvent, which results in achievement of a high graft modification efficiency at low cost without troublesome procedures.
