Multilayer elastomer films (multilayer material) comprising at least one continuous layer loaded with active chemical substance (such as anti-corrosives, lubricants or even biocides for medical use), inserted between inert elastomer barrier layers, methods of preparation and various applications of these films.n n n Said multilayer polymeric material, comprises at least one layer A consisting of a reversible or non-reversible gel, depending on the temperature, and loaded with at least one active chemical substance x and at least two barrier layers E , comprising an elastomer of synthesis e , the joining of said layers to each other being ensured by a polymeric bonding agent y , incorporated in at least one of said layers A or E and / or by an independent bonding layer Z , comprising a polymer z , and / or by a chemical or physical treatment of at least one of said layers A or E. |
