FIELD: chemistry.
SUBSTANCE: invention relates to forecasting in on-line mode and regulation of content in reactor of components of multimodal resin obtained by means of several catalysts in polymerisation reactors. Described are methods of estimation and periodic regulation of content of components in reactor during polymerisation of alpha-olefin with application of several catalysts which selectively include monomers and other reagents into polymer compositions.
EFFECT: ensuring quick determining of instant content of components in reactor and cumulative content of components in polymerisation reactors by application of novel linear ratio between introduction and content of components in reactor.
