摘要：
A polymeric resin having a density of greater than 0.960 g/cc, a melt index of from 1.3 g/10 min. to 2.8 g/10 min., a zero shear viscosity of from Ix 10 4 Pa*s to 1 x 10 5 Pa*s, a recoverable shear parameter of from 220 to 370, and a CY-a parameter of from 0.155 to 0.200. A polymeric resin having an initial tension defined by the equation IT>-1.67*(MI)+b where b is 5.17 and a percent decrease in the extrusion pressure of the resin of 30% when compared to polymer resin of similar melt index prepared with a catalyst that has not undergone an activation comprising an oxidation, reduction, oxidation sequence wherein the resin when formed into a film has a moisture vapor transmission rate of from 0.21 g.mil/100 in 2 /day to 0.33 g.mil/100 in 2 /day.
摘要（中）：
密度大于0.960g / cc，熔体指数为1.3g / 10min的聚合物树脂。 至2.8g / 10分钟，零剪切粘度为1×10 4 Pa * s至1×10 5 Pa * s，可恢复剪切参数为220至370，CY-a参数为0.155至0.200。 具有由等式IT> -1.67 *（MI）+ b定义的初始张力的聚合物树脂，其中b为5.17，并且与用相同熔体指数制备的类似熔体指数的聚合物树脂相比，树脂挤出压力的百分比降低30％ 没有经历活化的催化剂，其包含氧化还原氧化序列，其中当形成膜时树脂的水蒸气透过率为0.21g.mil / 100in2 / day至0.33g.mil / 100in2 / 天。
