    • The instant invention is an adhesion promoter system, and method of producing the same. The adhesion promoter system comprises an aqueous dispersion comprising the melt kneading product of: (a) at least 60 percent by weight of a base polymer, based on the total weight of the solid content, wherein said base polymer comprises a propylene/ethylene copolymer composition, wherein said propylene/ethylene copolymer has a crystallinity in the range of from 1 percent by weight to 30 percent by weight, a heat of fusion in the range of from 2 Joules/gram to 50 Joules/gram), and a DSC melting point in the range of 25° C. to 110° C.; (b) from 0.5 to less than 30 percent by weight of a functionalized polymer composition, based on the total weight of the solid content, wherein said functionalized polymer composition comprises homopolymers of propylene or copolymers of propylene with hexene, octene and/or other like alpha-olefins, the homopolymers or copolymers having a single unsaturation, a terminal succinic anhydride moiety, and additional succinic anhydride substitutions on the polypropylene backbone, where the succinic anhydride substitution ranges from about 5 to about 45 weight percent of functionalized polymer composition; (c) from 0.1 to less than 20 percent by weight of a stabilizing agent, based on the total weight of the solid content; and (d) in the presence of water and optionally one or more neutralizing agents, for example, at a temperature in the range of 25° C. to 200° C.
