摘要：Disclosed are graft copolymers of polyolefins and a method of preparing saidgraft copolymers. The method comprises irradiating a mass of olefin polymer particles

and thereafter treating the mass of particles with a vinyl monomer in liquid form. Anonoxidizing environment is maintained throughout the process while free radicalsproduced in the olefin polymer by the irradiation are present, thereby preventingdegradation of the polymer. In a final step, residual free radicals are deactivated, and anyunreacted monomer is removed.
