ABSTRACT:
Anhydride-functionalized polymers are modified in accordance with the present invention by reacting all or a portion of the anhydride functionality with an aliphatic alcohol to convert the anhydride groups to half-esters. Half-esters produced by modifying maleic anhydride grafted ethylene polymers with alcohols are particularly useful. Adhesive blends obtained by combining the alcohol-modified polymers with one or more polyolefin base resins and composite structures wherein said adhesive blends are adhered to EVOH are also provided. Modification of the maleic anhydride grafts in accordance with the process of this invention makes it possible to produce films having improved optical quality.
