摘要: Compositions are disclosed comprising (i) a high molecular weight base polymer, and (ii) a relatively low molecular weight ester copolymer comprising an olefin and a copolymerizable ester, wherein the ester copolymer has a pour point less than 400C. In certain embodiments, the high molecular weight base polymer and the relatively low molecular weight ester copolymer are both selected from ethylene-based copolymers such as ethylene-vinyl acetate and ethylene-n-butyl acrylate.
