摘要： An ethylene-based polymer characterized as having a density from about 0.9 to about 0.94 grams per cubic centimeter, a molecular weight distribution (Mw/Mn) from about 4 to about 10, a melt index (I2) from about 0.05 to about 2 grams per 10 minutes, a gpcBR value greater than 0.05 as determined by a gpcBR Branching Index and a Y value greater than 0.4 is disclosed. This ethylene-based polymer is especially useful for blending with other polymers such as LLDPE. When converting the blends into film, especially shrink film, the film shows good optics, good shrink tension, high stiffness, high tensile modulus, and tensile strength. When this resin is blended at with a LLDPE on a blown film line, improvements are seen in haze, gloss, clarity, and MD and CD tear as compared to a comparative LDPE.
摘要翻译：特征在于具有约0.9至约0.94克/立方厘米的密度，约4至约10的分子量分布（Mw / Mn），约0.05至约2克的熔体指数（I 2）每10分钟，公开了通过gpcBR分支指数测定的大于0.05的gpcBR值和大于0.4的Y值。该乙烯类聚合物特别适用于与其它聚合物如LLDPE共混。当将共混物转化成膜，特别是收缩膜时，该膜显示出良好的光学性能，良好的收缩张力，高刚度，高拉伸模量和拉伸强度。当将该树脂与吹塑薄膜生产线上的LLDPE共混时，与比较的LDPE相比，在雾度，光泽，透明度以及MD和CD撕裂方面都有改善。
