<p>Preparation of powder particles (I) of polyamide particles (PA), copolyamide (CoPA) or polyether block amide (PEBA), polyolefin, polyester or fluorocarbonated resins, grafted on a surface, comprises: mixing (I) with a functionalized grafting monomer; and photonic (gamma ) or electronic (beta ) irradiation of the impregnated powder of functionalized grafting monomer, at 0.5-15 Mrad. Independent claims are also included for: (1) a powder particle (I) of PA, CoPA, PEBA, polyolefin, polyester or fluorocarbonated resins, grafted on the surface by at least: a functionalized grafting monomer by a reactive function; or two functionalized grafting monomers each one functionalized by a different reactive function; and (2) a composition comprising (I).</p> |
