Adhesion promoter systems and methods of producing same, the systems including the admixing product of at least 60 percent by weight of a first functionalized polyolefin, and less than 40 percent by weight of a second functionalized polyolefin, based on the total weight of the solid content, and one or more solvents. The second functionalized polyolefin includes homopolymers of propylene or copolymers of propylene with hexene, octene and/or other alpha-olefins. The homopolymers or copolymers have a single unsaturation a terminal succinic anhydride moiety, and additional succinic anhydride substitutions on the polypropylene backbone. The succinic anhydride substitution ranges from about 5 to about 45 weight percent of second functionalized polyolefin.
