Abstract
Disclosed herein are methods for recovering a by-product stream of an ethylene oligomerization process, and systematically processing this stream in order to form a polymer composition that can be pelletized conventionally. This polymer composition can have a bimodal molecular weight distribution, which can be characterized by a ratio of the respective peak molecular weights ranging from 400:1 to 2000:1, and further, a liquid component of the polymer composition is in a range from 1 to 35 weight percent.
