PURPOSE:To produce a polymeric composite material of a uniform degree of grafting, by irradiating a polymeric material coated with an ultraviolet sensitizer with ultraviolet rays and contacting it with a vinyl monomer to perform graft copolymerization. CONSTITUTION:A polymeric material 1 such as PE, PP or a polyamide in the form of film, nonwoven fabric or woven fabric, fed from a feed roll 2 is put into a solution 3 of 0.2-10wt.% ultraviolet sensitizer (e.g., benzophenone) in an organic solvent to coat the polymeric material 1 with the ultraviolet sensitizer and led to an irradiation apparatus 4, where both surfaces of the polymeric material 1 are irradiated with ultraviolet rays of a wavelength of 200-600mum from a source of radiation. This polymeric material is put into water or a solution 7 of a vinyl monomer (e.g., acrylic acid in an organic solvent) in a concentration of 10-60wt.% to perform graft copolymerization, and the obtained polymeric composite material 8 is wound around a take-up roll 9.
