<p>Melt-reacted blends of ethylene/ carboxylic acid copolymers with metal oxides are improved by first incorporating the metal oxide into an ethylene copolymer of LDPE, HDPE, or LLDPE to form a concentrate or masterbatch, then melt-blending a minor amount of the concentrate into the ethylene/carboxylic acid copolymer thereby obtaining a uniform, homogeneous reaction of the metal oxide with the carboxylic acid groups. These melt-reacted blends provide tough molding resins. Especially preferred are melt-reacted blends of EAA with minor amounts of MgO/LLDPE concentrates.</p> |
