a laminate, the laminate comprising
a) a first substrate comprising a first substantially linear olefin copolymer;
b) an adhesion promoter superimposed on the first substrate, the adhesion promoter comprising a graft copolymer of a second substantially linear olefin copolymer;
c) a tackifying resin mixed with the adhesion promoter, or a binder superimposed on or mixed with the adhesion promoter;
d) a second substrate cemented onto the first substrate. The present invention is also an adhesion promoter comprising a copolymer derived from a C↓[2]-C↓[20] olefin and an ethylenically unsaturated carboxylic acid or anhydride, and a polar group functionalization Alkaline linear olefin copolymer or ethylene and C↓[3]- having a narrow molecular weight distribution, comonomer units randomly distributed along the polymer backbone and having a uniformity index of at least 75. A mixture of C↓[20] a copolymer of an α-olefin.
The laminates and adhesion promoters of the invention can be used in a variety of end uses, including bathroom gaskets, soles, carpet mats, and automotive windshields.
