    摘要： A polymer composition comprises at least an ethylene/α-olefin interpolymer and at least one other polymer. The other polymer can be selected from a second ethylene/α-olefin interpolymer, an elastomer, a polyolefin, a polar polymer, and an ethylene/carboxylic acid interpolymer or ionomer thereof. The ethylene/α-olefin interpolymer is a block copolymer having at least a hard block and at least a soft block. The soft block comprises a higher amount of comonomers than the hard block. The block interpolymer has a number of unique characteristics disclosed here. Also provided are gaskets, bottle cap liners, and closures that comprise or obtained from a compositon comprising at least one ethylene/α-olefin interpolymer and at least one polyolefin. The gaskets are capable of compression sealing various containers, without contaminating the contents. Liquid containers particularly benefit from the use of the novel gasket materials disclosed herein.

The high-density polyethylene composition of the instant invention includes a first component, and a second component. The first component is a high molecular weight ethylene alpha-olefin copolymer having a density in the range of 0.915 to 0.940 g/cm3, and a melt index (I21) in the range of 0.5 to 10 g/10 minutes. The second component is a low molecular weight ethylene polymer having a density in the range of 0.965 to 0.980 g/cm3, and a melt index (I2) in the range of 50 to 1500 g/10 minutes. The high-density polyethylene composition has a melt index (I2) of at least 1, a density in the range of 0.950 to 0.960 g/cm3, and g′ of equal or greater than 1. The method of producing a high-density polyethylene composition include the following steps: (1) introducing ethylene, and an alpha-olefin comonomer into a first reactor; (2) copolymerizing the ethylene with the alpha-olefin comonomer in the first reactor thereby producing a first component, wherein the first component being a high molecular weight ethylene alpha-olefin copolymer having a density in the range of 0.915 to 0.940 g/cm3, and a melt index (I21) in the range of 0.5 to 10 g/10 minutes; (3) introducing the first component and additional ethylene into a second reactor; (4) polymerizing the additional ethylene in the second reactor thereby producing a second component, wherein the second component being a low molecular weight ethylene polymer having a density in the range of 0.965 to 0.980 g/cm3, and a melt index (I2) in the range of 50 to 1500 g/10 minutes; and (5) thereby producing the high-density polyethylene composition, wherein the high-density polyethylene composition having a melt index (I2) of at least 1, a density in the range of 0.950 to 0.960 g/cm3, and g′ of equal or greater than 1.
