A process for improving the adhesiveness of a surface of a body fabricated from a polymeric material. The process comprises the step of irradiating said surface with an electron beam with an energy not greater than about 5 keV and at a partial pressure of oxygen in the range of from about 2 x 10-5 to about 2 x 10-3 Pa. Thebody so treated may be used in the manufacture of an article selected from the group comprising films, doors, covers, decks, cases, panels for use in the transportation industry, household electrical appliances, automobiles, telecommunications devices, business machines and packaging.
Méthode pour améliorer l'adhésivité de la surface d'un corps fabriqué à partir d'une matière polymérique. Le procédé comprend une étape d'irradiation de ladite surface par un faisceau d'électrons possédant une énergie d'au plus 5 keV, à une pression partielle d'oxygène se situant dans une plage d'environ 2 x 10-5 à 2 x 10-3 Pa. Le corps ainsi traité peut servir à fabriquer les articles et produits suivants : pellicules, portes, couvertures, ponts, caisses, panneaux pour l'industrie du transport, appareils électriques domestiques, automobiles, dispositifs de télécommunications, machines et emballages pour le secteur commercial, etc.
