Title:
ファイバー用途で使用するのに適したエチレン／α−オレフィンインターポリマー、およびそれから作製されたファイバー
Document Type and Number:
Japanese Patent JP5727615
Kind Code:
B2
Abstract:
The instant invention provides an ethylene/alpha-olefin interpolymer suitable for use in fiber applications, and fibers 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 from 0.920 to 0.965 g/cm3, and a melt index (I2) in the range of from 0.5 to 100 g/10 minutes, and melt flow ratio (I10/I2) in the range of from 5.8 to 8.
