METHOD FOR POLYOLEFIN TRANSFER IN CONTINUOUS POLYMERIZATION REACTORS

摘要

The present invention relates to a method for transferring reactants between reactors in a method for producing a polyolefin resin such as polypropylene using catalysts. More specifically, the present invention relates to a method for effectively transferring reactants when transferring reactants between reactors, while suppressing stagnation of the reactants and also inhibiting a change in a composition of a rear end reactor caused by the reactant of a front end reactor, if the reactants in the front end reactor and a gaseous or liquid composition in the rear end reactor are transferred together to the rear end by pressure difference between the two reactors.
