Abstract

Succinic acid or succinic anhydride grafts of HDPE are blended with ungrafted LLDPE and with ungrafted LDPE to form blends having useful adhesive properties. The succinic acid or succinic anhydride groups are provided by grafting, respectively, maleic acid or maleic anhydride onto HDPE. Laminates of the blends on various metals and polymers are shown.
