Способ полимеризации по крайней мере одного олефина, согласно которому используют по крайней мере два реактора полимеризации, полимеризуют часть олефина в одном из реакторов в присутствии катализатора, состоящего из бис(циклопентадиенил)хрома, в известных случаях замещенного, извлекают из этого реактора композицию, включающую полимер и катализатор, и вводят эту композицию и другую часть олефина в другой реактор, причем по крайней мере в один из реакторов вводят водород.The method of polymerizing at least one olefin, according to which at least two polymerization reactors are used, part of the olefin is polymerized in one of the reactors in the presence of a catalyst consisting of bis (cyclopentadienyl) chromium, in some cases substituted, the composition comprising and a catalyst, and this composition and another part of the olefin are introduced into another reactor, with hydrogen being introduced into at least one of the reactors.
