    Abstract: The invention relates to adhesive compositions having a modified polyethylene; an unmodified polyethylene of a certain density and a styrene-based elastomer. The styrene-based elastomer is present in a weight percentage of 10 to 45 wt. percent relative to the total weight of the elastomer plus the modified and unmodified polyethylenes. The adhesive composition is particularly useful in multilayer composite structures having polypropylene as one substrate and having bonded thereto a polyethylene or a layer which is made from an ethylene copolmer such as an ethylene/acid copolymer or an ethylene acid ionomer. In addition, the adhesive composition is particularly useful in multilayer structures having five layers wherein a single adhesive composition is needed as layer two and four and the other structural layers are, for example, polyethylene/nylon/polypropylene or similar structures which would heretofore require two different polyolefin base adhesives.

    Abstract translation: 本发明涉及具有改性聚乙烯的粘合剂组合物; 一定密度的未改性聚乙烯和苯乙烯类弹性体。 苯乙烯类弹性体的重量百分比为10〜45重量%。 百分数相对于弹性体加上改性和未改性的聚乙烯的总重量。 粘合剂组合物特别可用于具有聚丙烯作为一个基材并且与聚乙烯接合的多层复合结构体或由乙烯共聚物如乙烯/酸共聚物或乙烯酸离聚物制成的层。 此外,粘合剂组合物特别可用于具有五层的多层结构,其中需要单一粘合剂组合物作为第二层和第四层,而其它结构层例如是聚乙烯/尼龙/聚丙烯或类似的结构,其将需要两个 不同的聚烯烃基粘合剂。
