There is provided a technique for introducing grafted side chains having a narrow molecular weight distribution onto a molded organic polymer substrate, for example polyolefin substrate, while maintaining the form of the substrate. One aspect of the present invention relates to a method of manufacturing a grafted material, comprising the steps of (a) irradiating an organic polymer substrate with ionizing radiation, and then bringing a polymerizable monomer and a polymerization initiating group-introducing agent into contact with the substrate, thus introducing grafted side chains having polymerization initiating groups on ends thereof onto trunk polymer of the substrate, and (b) then bringing a polymerizable monomer into contact with the substrate, thus causing the grafted side chains to grow.

A method for manufacturing a grafted material comprising the steps of (a) irradiating an organic polymer substrate with ionizing radiation while a polymerizable monomer and a polymerization initiating group-introducing agent have been brought into contact with the substrate, thus introducing grafted side chains having polymerization initiating groups on ends thereof onto trunk polymer of the substrate, and (b) then bringing a polymerizable monomer into contact with the substrate, thus causing the grafted side chains to grow.
A grafted material having, on trunk polymer of an organic polymer substrate, grafted side chains for which the molecular weight distribution has been controlled to be narrow.
A grafted material having, on trunk polymer of an organic polymer substrate, grafted side chains at least part of which has been formed through living polymerization.
