Description
ひとつの実施形態では、第2微細孔層材は、(i) Mwが少なくとも約1×106 (UHMWPE-2)の第4ポリエチレン、(ii) Mwが1×106未満の第3ポリエチレンと、UHMWPE-2と、第4ポリエチレンであって、第4ポリエチレンの量が第3及び第4ポリエチレンの総重量に対し少なくとも約8wt%である材料、または(iii) UHMWPE-2及びPP-2、または(iv) PE-2、UHMWPE-2及びPP-2の内の、いずれかから成る。
上記の(ii), (iii)及び(iv)のひとつの実施形態では、高強度の多層微細孔ポリオレフィン膜を製造するために、UHMWPE-2は、UHMWPE-2, PE-2及びPP-2の総重量に対し少なくとも約8wt%、または少なくとも約20 wt%、または少なくとも25 wt%含まれる。
上記の(iii)及び(iv)のひとつの実施形態では、PP-2少なくともホモポリマーまたはコポリマーのいずれかであり、第2微細孔層材の総重量に対し25wt%以下含まれ、または約2%から約15%の範囲で含まれ、または約3%から約10%の範囲で含まれる。
ひとつの実施形態では好ましいPE-2はPE-1と同一であるが、独立して選択することもできる。ひとつの実施形態では、好ましいUHMWPE-2はUHMWPE-1と同一であるが、独立して選択することもできる。
In one embodiment, the second microporous layer material comprises (i) a fourth polyethylene having an Mw of at least about 1 × 10 6 (UHMWPE-2), and (ii) a third polyethylene having an Mw of less than 1 × 10 6 UHMWPE-2 and a fourth polyethylene, wherein the amount of the fourth polyethylene is at least about 8 wt% based on the total weight of the third and fourth polyethylene, or (iii) UHMWPE-2 and PP-2, Or (iv) any of PE-2, UHMWPE-2 and PP-2.
In one embodiment of (ii), (iii) and (iv) above, UHMWPE-2 is used to produce a high strength multilayer microporous polyolefin membrane, such as UHMWPE-2, PE-2 and PP-2. At least about 8 wt%, or at least about 20 wt% , or at least 25 wt%, based on the total weight of
In one embodiment of the above (iii) and (iv), PP-2 is at least either a homopolymer or a copolymer, and is contained in an amount of 25 wt% or less based on the total weight of the second microporous layer material, or about 2 From about% to about 15%, or from about 3% to about 10%.
In one embodiment, the preferred PE-2 is the same as PE-1, but can also be selected independently. In one embodiment, the preferred UHMWPE-2 is the same as UHMWPE-1, but can also be selected independently.
