摘要：Provided are compositions comprising an ethylene acid copolymer and afunctional ethylene copolymer. The ethylene acid copolymer comprises inchainpolymerized units derived from ethylene and at least one ethylenically unsaturatedmonocarboxylic acid or derivative thereof. The functional ethylene copolymer comprisesin-chain polymerized units derived from ethylene and at least one ethylenicallyunsaturated dicarboxylic acid or derivative thereof. Optionally, the ethylene acidcopolymer or the functional ethylene copolymer further comprises one or morecopolymehzed alkyl (meth) acrylates. The carboxylic acid functionalities of the ethyleneacid copolymer and the functional ethylene copolymer may be at least partially
neutralized to form carboxylate anions. Preferred countehons include one or more alkalimetal, transition metal, or alkaline earth metal cations. The compositions are useful forfabricating films, sheets and other shaped articles, such as packages.
