PROCESS FOR PRODUCING CHEMICAL REACTIONS IN A POLYMER FILM

摘要

P Process for the production of chemical reactions in a polymer film BR/ This process of direct production, of chemical reactions in a polymer film (18), to a certain depth inside the film, is characterized in that it comprises the following steps: BR/ - positioning the polymer film (18) on the path of a beam (14) of particles, BR/ - selecting the nature of the particles of the beam in function their reactivity with the functional groups and the polymer backbone, BR/ - determine the energy to be communicated to the particles of the beam as a function of the depth of the zone where the reaction is to be carried out inside of the polymer film, BR/ - irradiating the polymer film with a beam (14) of the selected particles, having the energy determined in the previous step. / P
