ABSTRACT:
Succinic acid or succinic anhydride grafts of HDPE are blended with LLDPE, especially ethylene/1-octene copolymers, to form blends having useful adhesive properties at elevated temperatures. The succinic acid or succinic anhydride groups are provided by grafting, respectively, maleic acid or maleic anhydride onto HDPE. The resin blends are useful for coating metal foil substrates. The adhesion of the resin blend to the metal foil substrate is particularly good at elevated temperatures (e.g., temperatures above about 60.degree. C.).
