PURPOSE:To graft-polymerize any desired acetylene derivative with a polymer molding, by irradiating the polymer molding in contact with halogen molecules with light and again with light in the presence of a vapor of an acetylene derivative. CONSTITUTION:A polymer molding (e.g., PE film) in the form of, preferably, a film, sheet or fiber is contacted with halogen molecules and irradiated with ultraviolet rays, visible light, sunlight or the like to obtain a halogenated polymer molding (A). Component A is irradiated again with light in the presence of a vapor (B) of an acetylene derivative and, optionally, a photosensitizer (e.g., acetophenone).
