摘要: A method of manufacturing a polymer composition that includes initiating a polymerization reaction at an initial set of polymerization parameters, determining an instantaneous split of the at least one property of an intermediate polymer composition, and adjusting the initial set of polymerization parameters based on the instantaneous split of the at least one property to obtain a desired distribution of the at least one property in the polymer composition.

摘要: The present method is directed to techniques for estimating and periodically controlling the reactor split of alpha-olefin polymerizations using multiple catalysts that selectively incorporate monomers and other reactants into polymer compositions. The method provides for the rapid determination of instantaneous reactor split and cumulative split in polymerization reactors by the use of a novel linear relationship between Incorporation and Reactor Split.
