Реферат: The invention relates to a method of polymerizing olefins in a fluidized-bed polymerization reactor in which olefin monomers are polymerized in a fluidized bed formed by polymerizing particles containing the polymerization catalyst, said fluidized bed being maintained in fluidized state by introducing to the reactor (10) at least one circulating gas flow containing polymerizable monomers and optionally hydrogen, inert gases or a diluent gas, and said fluidized bed being stirred by virtue of at least one agitator means, which is attached to an essentially vertical drive shaft (19, 20). According to the invention, at least a portion of the gas flow introduced to the reactor (10) is passed to the reactor via at least one flow channel provided to the interior of said shaft (20) and said agitator means (21, 22).
