収縮フィルム用途での使用に好適なエチレン/アルファ-オレフィン共重合体、及びそれから製造される物品

Japanese Patent JP2013538915

A

The instant invention provides an ethylene/alpha-olefin interpolymer suitable for use in shrinkage film applications, and articles made therefrom. The ethylene/alpha-olefin interpolymer according to the present invention has a CDBI of less than 60%, and comprises at least two fractions in crossfractionation of the ethylene/alpha-olefin interpolymer, eluting from 85° C. to 90° C. and from 90° C. to 95° C., comprising a weight fraction ratio of >0.68 and a molecular weight homogeneity index of greater than 0.65; wherein the weight fraction ratio is the ratio of the weight of polymer in each fraction divided by the weight of polymer eluting between 95° C. and 100° C. and the molecular weight homogeneity index is the ratio of the weight average molecular weight of the polymer in the fraction divided by the weight average molecular weight of the polymer eluting between 95° C. and 100° C., and wherein the ethylene/alpha-olefin interpolymer has a density in the range of 0.920 to 0.940 g/cm3.
