    Abstract: Methods of tailoring polyethylenes are contemplated utilizing 0.5 to 70 volume percent oxygen containing gases. The tailoring occurs in a melt-conveying zone of a mixer/extruder, and not in the feed or melting zones of a mixer/extruder. The effect of tailoring is to decrease the haze and/or increase the gloss of blown films made from the tailored polyethylenes compared to similar polyethylenes that are extruded/mixed in the substantial absence of oxygen or oxygen containing gases.

    Abstract translation: 考虑使用0.5至70体积％含氧气体来调节聚乙烯的方法。 剪切发生在混合器/挤出机的熔体输送区域中，而不是在混合器/挤出机的进料或熔融区域中。 与基本上不含氧气或含氧气体挤出/混合的类似聚乙烯相比，定制的效果是降低由定制的聚乙烯制成的吹塑薄膜的雾度和/或增加的光泽度。
