Abstract: A large number of free radicals are produced on the surface of PEto be irradiated by plasma, the ESRmeasurement for this kind of radicals in vacuum showed a five -line spectrum, which can be assigned to the free radical -CH2CH2·The radical translate to a peroxide free radical as it contacts with air, and to a PMMA free radical as it contacts with monomer MMA The results show that the free radical on the surface of PEto be irradiated by plasma can initiate the graft copolymerization of monomer MMA The graft amount measured by IRspectra increases with postpolymerization time, and reaches as highly as 10% (weight ratio)The stability of the PMMA free radicals, and the dependence of the graft amount on postpolymerization time indicate the graft chain has activity and the free radical in the chain end does not terminate.

Key words: Plasma, Surface, Surface free radical, Graft copolymerization
