    摘要： a. a first co-extruded polymeric layer comprising an ionomer resin of ethylene having a comonomer content between 8-25% by weight, based on the weight of the copolymer, of a C3-C8 alpha,ß-ethylenically unsaturated mono-carboxylic acid with at least 35% of the acid moieties neutralized with metal ions; a. a second co-extruded polymeric layer selected from an ionomer resin, an ethylene acid polymer, an ethylene copolymer, an ethylene acid terpolymer or a metallocene catalyzed very low density polyethylene (m-VLDPE) and optionally, contains pigments, dyes, flakes, additives and any mixtures thereof; and b. a third co- extruded polymeric adhesive layer of metallocene catalyzed very low density polyethylene (m-VLDPE); and c. optionally, at least one additional co-extruded fourth thermoformable polymeric layer or backing layer of for example, polypropylene, co-polymers of polypropylene, random polymers of polypropylene, blends polypropylene and other polyolefins that is in contact with and adhered to the third co-extruded layer; another aspect of this invention is that the second layer can be m-VLDPE and can contain pigments, dyes and other additives and be directly co- extruded with a third thermoformable polymer to form a three layered structure; another structure is a two layered structure in which the first layer is an ionomer resin as described above and the second layer is m-VLDPE directly co-extruded with the first layer and contains pigments, dyes and other additives; any of the above structures can be thermoformed and cladded with an appropriate engineering resin to form parts and panels for automobiles, trucks and recreational vehicle and the above two, three or four layer structures can be laminated to another thermoplastic resin to form films or laminates that have a wide variety of end uses.

    摘要翻译： 一个。 第一共挤出聚合物层，其包含基于共聚物重量的8-25重量％的共聚单体含量的乙烯的离聚物树脂，C3-C8α，β-烯属不饱和一元羧酸与 至少35％的酸部分用金属离子中和; 一个。 选自离聚物树脂，乙烯酸聚合物，乙烯共聚物，乙烯酸三元共聚物或金属茂催化的极低密度聚乙烯（m-VLDPE）的第二共挤出聚合物层，并且任选地包含颜料，染料，薄片，添加剂 及其任何混合物; 和b。 茂金属催化的非常低密度聚乙烯（m-VLDPE）的第三共挤聚合物粘合剂层; 和c。 任选地，至少一个另外的共挤出第四可热成形聚合物层或背衬层，例如聚丙烯，聚丙烯的共聚物，聚丙烯的无规聚合物，共混聚丙烯和其它聚烯烃，其与第三共聚物 挤压层; 本发明的另一方面是第二层可以是m-VLDPE并且可以含有颜料，染料和其它添加剂，并与第三可热成型聚合物直接共挤出以形成三层结构; 另一种结构是两层结构，其中第一层是如上所述的离聚物树脂，第二层是与第一层直接共挤出的m-VLDPE，并含有颜料，染料和其它添加剂; 任何上述结构可以用适当的工程树脂热成型和包覆以形成用于汽车，卡车和休闲车辆的部件和面板，并且可以将上述两个，三层或四层结构层压到另一种热塑性树脂上以形成薄膜或层压板， 有各种各样的最终用途。
