Abstract: Apparatuses and processes that produce multimodal polyolefins, and in particular, polyethylene resins, are disclosed herein. This is accomplished by using two reactors in series, where one of the reactors is a multi-zone circulating reactor that can circulate polyolefin particles through two polymerization zones optionally having two different flow regimes so that the final multimodal polyolefin has improved product properties and improved product homogeneity.

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.

Abstract: Methods of controlling olefin polymerization reactor systems may include a) selecting n input variables, each input variable corresponding to a process condition for an olefin polymerization process; b) identifying m response variables corresponding to a measurable polymer property; c) adjusting one of more of the n input variables using the olefin polymerization reactor system and measuring each of the m response variables as a function of the input variables for olefin polymers; d) analyzing the change in each of the response variables as a function of the input variables to determine coefficients; e) calculating a Response Surface Model (RSM) for each response variable determined in step d); f) applying n selected input variables to the calculated RSM to predict one or more of m target response variables; and g) using the n selected input variables to operate the olefin polymerization reactor system and provide a polyolefin product.
