The invention relates to an elastomeric laminate comprising a layer A, a layer B, n layers Ci arranged between the layers A and B, n being an integer greater than or equal to 2, i being an integer ranging from 1 to n, the layer C1 being arranged between the layers A and C2, the layer Cn arranged between the layers B and Cn-1, the layer Ci arranged between the layers Ci-1 and Ci+1 for i from 2 to n-1 when n is greater than 2. The layer A comprises a diene elastomer matrix, the constituent repeating units of which contain more than 75 mol% of hydrocarbon-based units, the layer B comprises a polar elastomer which contains ethylene units and vinyl acetate units. For i from 1 to n, the layer Ci comprises a highly saturated diene elastomer which has more than 50 mol% of ethylene units and from 0to less than 100 phr of polar elastomer. In the layer C1, the content of highly saturated diene elastomer is higher than the content of polar elastomer. In the layer Cn, the content of polar elastomer is higher than the content of highly saturated diene elastomer. The elastomeric laminate has good resistance to separation of the layers which constitute it.

    本发明涉及弹性体层压件,所述弹性体层压件包括层A、层B,和布置在层A和层B之间的n个层Ci,n为大于或等于2的整数,i为1至n的整数,层C1布置在层A和层C2之间,层Cn布置在层B和层Cn‑1之间,当n大于2时,对于i为2至n‑1,层Ci布置在层Ci‑1和层Ci+1之间。所述层A包含二烯弹性体基质,所述二烯弹性体基质的结构重复单元含有大于75摩尔%的烃基单元,所述层B包含极性弹性体,所述极性弹性体含有乙烯单元和乙烯乙酸酯单元。对于i为1至n,所述层Ci包含高度饱和二烯弹性体和0至小于100phr的极性弹性体,所述高度饱和二烯弹性体具有大于50摩尔%的乙烯单元。在层C1中,高度饱和二烯弹性体的含量高于极性弹性体的含量。在层Cn中,极性弹性体的含量高于高度饱和二烯弹性体的含量。所述弹性体层压件具有良好的构成所述弹性体层压件的层的耐分离性。
