    摘要: 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.

    摘要: The present invention relates to an ethylene/α-olefin interpolymer product comprising at least one α-olefin interpolymerized with ethylene and, characterized in at least one aspect, as having improved properties when utilized in a hot melt adhesive formulation. The invention also relates to a process for manufacturing the interpolymer product wherein the process comprises employing two or more single site catalyst systems in at least one reaction environment (or reactor) and wherein the at least two catalyst systems have (a) different comonomer incorporation capabilities or reactivities and/or (b) different termination kinetics, both when measured under the same polymerization conditions. The interpolymer products are useful, for example, in applications such as hot melt adhesives, and also for impact, bitumen and asphalt modification, adhesives, dispersions or latexes and fabricated articles such as, but not limited to, foams, films, sheet, moldings, thermoforms, profiles and fibers.
