POLYMER MIXTURES FOR USE IN MULTIPLE LAYER STRUCTURE AND MULTIPLE LAYER STRUCTURES THAT UNDERSTAND THE SAME

摘要

the present invention provides mixtures of polymers that can be used in a multilayer structure and multilayer structures that comprise one or more layers formed from such mixtures. in one aspect, a polymer blend comprises (a) a copolymer comprising ethylene and at least one of acrylic acid and methacrylic acid having an acid content of 2 to 21 weight percent based on the weight of the copolymer, wherein the amount of copolymer (a) comprises 20 to 80 weight percent of the mixture based on the total weight of the mixture and (b) a copolymer comprising ethylene and at least one of methyl acrylate and ethyl acrylate which has a content of 5 to 30 weight percent acrylate based on the weight of the copolymer, where the amount of copolymer (b) comprises 10 to 50 weight percent of the mixture based on the total weight of the mixture, where the amount of copolymer (b) a) and copolymer (b) is at least 70 percent by weight of the mixture based on the total weight of the mixture.
