摘要： The subject of the invention is a process for producing polyamide, copolyamide, polyolefin, copolyester amide or fluorocarbon resin powder particles on to the surface of which has been grafted at least one functionalized grafting monomer, characterized in that it comprises: a) a step of blending the polyamide or copolyamide powder particles with the functionalized grafting monomer; followed by b) a step of irradiating the powder impregnated with functionalized grafting monomer resulting from a) with photons (γ-radiation) or electrons (β-radiation), with a dose ranging from 0.5 to 15 Mrad. The invention also relates to the particles grafted in this way and to the compositions containing such particles.
