| titleOfInvention | PVC MEMBRANE WITH REDUCED PLASTICIZER MIGRATION |
| abstract | 1. The membrane (1) containing the insulating layer (2), which contains more than 50 wt.% PVC relative to the total mass of the insulating layer, and the barrier layer (3), while the barrier layer (3) is: a barrier layer S1 (31), while the barrier layer S1 (31) contains a layer of polyvinyl alcohol (4), which contains more than 50 wt.% Copolymer of RA in relation to the total weight of the layer of polyvinyl alcohol (4), and which is associated with the sealing layer (2) using a polyurethane layer (5), while the polyurethane layer (5) consists of more than 10 wt.% polyurethane PUR in relation to the total mass of the polyurethane layer (5); the barrier layer S2 (32), wherein the barrier layer S2 (32) consists of a composition containing 5-50 wt.% PUR polyurethane and 50-95 wt.% RA copolymer; and wherein the PUR polyurethane contains at least one nucleophilic functional group selected from the group consisting of a hydroxyl group, a carboxyl group, a sulfonate group and a phosphate group, and wherein the RA copolymer is a copolymer of ethylene and vinyl alcohol. 2. The membrane (1) according to claim 1, characterized in that the ethylene content in the RA copolymer is 20-50 mol%, in particular 25-40 mol%, and most preferably 29-38 mol%. 3. The membrane (1) according to claim 1, characterized in that the PUR polyurethane is obtained from at least one polyisocyanate and at least one polyol, as well as at least one M1 monomer, wherein the M1 monomer contains at least one nucleophilic functional group and monomer M1 contains at least one isocyanate group or a group that is reactive with isocyanate groups. The membrane (1) according to claim 3, characterized in that the monomer M1 contains a carboxyl group and / or a sulfonate group as |
