Tensile strengths of polyethylene-difunctional monomer systems irradiated to doses up to 4.6 Mrads (Co/sup 60/ source) were measured. Polyethylene-allyl methacrylate (equilibrium swollen) systems irradiated to 1.5 Mrads have tensile strengths at 100 deg C equal to that of monomer-free polyethylene irradiated to 15 Mrads. Polyethylene-allyl acrylate and polyethylene-allyl methacrylate irradiated to 4.6 Mrads have higher tensile strengths than monomerfree polyethylene after 75 Mrads. Ten tensile strength of polyethylene equilibrium swollen with either of these two monomers prior to Co/ sup 60/ irradiation rises markedly at the low doses tested. No dose rate dependency for gel content was observed for polyethylene equilibrium-swollen with allyl methacrylate between 0.015 and 0.21 Mrads/hr. (auth)
