PURPOSE:To readily obtain a photopolymerized substance in a short time, by sealing a radically polymerizable monomer and sensitizer, etc., in a tare prepared from an ultraviolet ray transmitting high polymer film, irradiating the sealed monomer, etc., with ultraviolet rays from the outside of the tare and photopolymerizing the monomer. CONSTITUTION:A radically polymerizable monomer [e.g. styrene or methyl (meth)acrylate] and a sensitizer (e.g. benzoyl peroxide, azobisisobutyronitrile, diphenyl monosulfide or CCl4) are sealed in a tare prepared from an ultraviolet ray transmitting high polymer film (e.g. a film or laminated film of polyvinyl chloride, polytrifluoroethylene or polystyrene) and then irradiated with ultraviolet rays (preferably 200-500nm wavelength) from the outside of the tare to carry out photopolymerization, normally at -20-+100 deg.C temperature. Furthermore, the amount of the sensitizer used is preferably 0.01-5wt.% based on the monomer.
