Abstract
Abstract A process for graft polymerization of monomers onto organic macromolecular solid materials which comprises activating a macromolecular shaped article having a specific surface area of less than 3800 cm2/g with ozone under a condition of any point of the area defined by straight lines connecting p1, c1, c10, p10 in the attached FIG. 1, and further bringing said ozone activated material into contact with one or more radical polymerizable monomers in the presence of one or more members selected from the group consisting of trimethylamine, propylamine, ethylenediamine, piperidine, piperazine, morpholine, ethanolamine, hydroxyethyl ethylenediamine, pyridine, formamide and dimethyl formamide.
