PURPOSE: To freely and readily control physical properties of various organic compounds according to uses and improve the physical properties, by converting an active substance, e.g. metal, etc., into an ionic or radical state, coating an organic compound with the active substance or injecting the substance into the compound.
CONSTITUTION: An active substance, e.g. metal, etc., ionizable or convertible into a radical state is converted into an ionic or radical state preferably by irradiation with vaporized electron beams. The surface of an organic compound is then coated with the resultant substance or injection of the substance into the interior of the organic compound is carried out to change physical properties of the organic compound. Physical properties, e.g solubility in water, dispersibility, safety for bodies, elasticity, strength, etc., of various organic compounds, e.g. synthetic resin, rubber, dye, pigment, yeast, protein, vitamin, etc., can be freely controlled extremely readily by this method as compared with a well-known method and the above-mentioned physical properties can be remarkably improved.
