摘要： Ethylene copolymer compositions having a density of 0.902 g/cm3 or less exhibit rapid crystallization behavior. The ethylene copolymer compositions comprise a first ethylene copolymer, a second ethylene copolymer and optionally a third ethylene copolymer, where the number average molecular weight of the first ethylene copolymer is greater than the number average molecular weight of the second ethylene copolymer. The ethylene copolymer compositions are useful in the formation of monolayer and multilayer films.

摘要： Ethylene copolymer compositions having a density of from 0.860 to 0.910 g/cm3 exhibit rapid crystallization behavior. The ethylene copolymer compositions comprise a first ethylene copolymer, a second ethylene copolymer and a third ethylene copolymer, where the number average molecular weight of the first ethylene copolymer is greater than the number average molecular weight of the second ethylene copolymer and the third ethylene copolymer. The ethylene copolymer compositions are useful in the formation of monolayer and multilayer films.
