Abstract:
1. A process for the surface treatment of a plastic comprising the following stages: (1) application, to at least one of the surfaces of the plastic, of a composition with reactive functional groups which can be polymerized and/or crosslinked comprising: A1) monomers with oxetane and alkoxy functional groups, oxetane and hydroxyl functional groups, or oxetane and alkoxysilyl functional groups of formula: in which: R R A2) monomers comprising carboxyl and oxetane functional groups or comprising oxetane and alkoxysilyl functional groups of formula: in which: A3) difunctional oxetane monomers of formula: in which: (2) and polymerization and/or crosslinking of the treated surface by its exposure under a source of irradiation and/or under electron beam(s), wherein the matrix A additionally comprises polyorganosiloxanes A4), which are composed of units of formula (II) and are terminated by units of formula (Ill) and/or are cyclic and comprise units of formula (II), which formulae are represented below: in which: the R the Z symbols, which are alike or different, represent:
