A process for producing powder particles of polyamide, copolyamide, polyether block amide, polyolefin, polyester or fluorocarbon resin having graft chains on the surface, grafted powder particles, and a composition comprising the powder particles. The method comprises the steps of (a) and (b): (a) mixing the powder particles with at least one functionalized graft monomer; (b) the functionalization obtained in step (a). A step of irradiating the powder particles impregnated with the graft monomer with light irradiation (γ rays) or electron beams (β rays) at a dose of 0.5 to 15 Mrad. [Selection figure] None |
