摘要

Method to estimate line of division of reactor for multimodal polyolefins. The present invention relates to techniques for estimating and controlling, from time to time, division of reactor of alpha - olefin polymerizations using multiple catalysts that incorporate selectively monomers and other reagents in polymer compositions.The method provides rapid determination of instantaneous and cumulative reactor division division in polymerization reactors, by use of linear relationship between the incorporation and inventive division of reactor.
