The invention relates to a method for depositing an adherent layer of a PVC copolymer on a substrate, characterized in that it comprises the steps of:. formation, in an organic solvent, of a mixture of precursors of the copolymer comprising PVC and 0.1 to 2% by weight of an organotrialkoxysilane corresponding to the formula: H (HN - R1) x HN - R2 - Si - ( OR3) 3, in which: - R1 and R2 are alkyl or aromatic intercalary groups, - R3 is an alkyl group, the three substituents R3 not being the same, and - x is between 0 and 2 ,. depositing a layer of this mixture on the substrate ,. drying the mixture to evaporate the solvent, and. heating the assembly thus obtained to a temperature of between 70 and 170 degreC, for a time of between 3 hours and 5 minutes respectively. |
