摘 要：
FIELD: chemistry.;SUBSTANCE: invention relates to production of polyolefin. Described is a method of preparing a polyolefin composition. The method is realised by reacting one or more olefin monomers in a single reactor. The reactor contains a bicomponent catalyst system and a chain-transfer agent. The method involves a step of changing concentration of the chain-transfer agent in the reactor in order to control high-boiling and low-boiling
fractions of the polyolefin composition. At least one condition in the reactor is controlled in order to change molecular weight distribution. Change in distribution results in the reverse direction of the melt flow index of the polymer and change in the second direction.;EFFECT: reduction in melt flow index with reduction in concentration of the chain-transfer agent.;22 cl, 6 dwg, 2 tbl, 2 ex
