摘要:
The invention provides an ethylene-based interpolymer comprising the following features: a) density from 0.910 to 0.930 g/cc; b) melt index (I2) from 0.1 to 0.5 g/10 min; and c) a high density fraction in an ATREF short chain branch distribution (SCBD) curve, eluting above 92° C., of greater than 10 percent to less than 28 percent of the total ATREF SCBD curve area. The invention also provides a composition comprising an ethylene-based interpolymer that comprises the following features: a) a density from 0.919 to 0.928 g/cc; b) a melt index (I2) from 0.1 to 0.8 g/10 min; and c) a high density fraction in an ATREF short chain branch distribution (SCBD) curve, eluting above 92° C., of greater than 10 percent to less than 28 percent of the total ATREF SCBD curve area. The invention also provides a hollow tube comprising at least one component formed from a composition comprising an ethylene-based interpolymer that comprises the following features: a) a density from 0.919 to 0.928 g/cc; b) a melt index (I2) from 0.1 to 0.8 g/10 min; and c) a high density fraction in an ATREF short chain branch distribution (SCBD) curve, eluting above 92° C., of greater than 10 percent to less than 28 percent of the total ATREF SCBD curve area; and wherein the tube has a hydrostatic design basis (HDB) of at least 1000-psi at 23° C. per ASTM D-2837 regression method.
