摘要: 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.

摘要: A polymerization catalyst system and polymerization processes using the catalyst systems are disclosed. The polymerization catalyst systems may include a) a first catalyst compound, and b) a second catalyst compound, wherein the first catalyst compound includes an oxadiazole-containing compound. In some embodiments, the oxadiazole-containing compound has essentially no hydrogen response, thus allowing better and/or tailored control of product properties when producing polymers using the catalyst system.
