ABSTRACT:
The present invention is a laminate comprising a first substrate adhesively bonded to a second substrate through an adhesion promoter. The first substrate comprises a substantially linear olefin copolymer and the adhesion promoter comprises a polar group functionalized substantially linear olefin copolymer. The present invention is also an adhesion promoter that comprises a mixture of a copolymer of a C.sub.2-20 olefin and an ethylenically unsaturated carboxylic acid or acid anhydride and a polar group functionalized substantially linear olefin copolymer or a polar group functionalized copolymer of ethylene and a C.sub.3-20 olefin having a narrow molecular weight distribution, a random distribution of comonomer units along the polymer backbone, and a homogeneity index of at least 75. The present invention is useful in a variety of applications such as bathroom scales, shoe soles, carpet-backing, and automobile windshields.
