Рассчитаны отношения констант скоростей реакций переноса полимерной цепи с мономером, триэтилалюминием (AlEt3), триизобутилалюминием и водородом к константе скорости реакции роста цепи. Полученные данные позволяют оценить влияние отдельных реакций переноса цепи на молекулярную массу полимера при различных условиях полимеризации и целенаправленно выбирать условия полимеризации для получения полигексена с требуемой молекулярной массой. Найдена неоднородность активных центров в реакции переноса цепи с водородом при использовании сокатализатора AlEt3, приводящая к изменению полидисперсности полимера при изменении концентрации водорода в реакционной среде. Выполнен анализ кривых молекулярно-массового распределения полигексена путем их разложения на компоненты Флори для образцов полигексена с различной полидисперсностью.</p></abstract><trans-abstract xml:lang="en"><p>The influence of concentrations of the monomer, triethylaluminum, and hydrogen on the molecular mass of polyhexene obtained by polymerization of hexene-1 over a supported titanium-magnesium catalyst was studied. Ratios of rate constants of the transfer of polymer chain with the monomer, triethylaluminum (AlEt3) and hydrogen to the rate constant of the chain-growth were calculated.</p><p>The data obtained allowed the contribution of individual reactions of chain transfer to molecular mass of the polymer to be estimated at various polymerization conditions and the polymerization conditions to be chosen deliberately in order to synthesize polyhexene with the required molecular mass. The discovered inhomogeneity of the centers active to the chain transfer with hydrogen in the presence of the AlEt3 co-catalyst caused changes in the polymer polydispersion upon changes in the hydrogen concentration in the reaction medium. Curves of the polyhexene molecular mass distribution in polyhexene samples with different polydispersion were analyzed using their resolution into Flory components.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полигексен</kwd><kwd>молекулярная масса</kwd><kwd>молекулярно-массовое распределение</kwd><kwd>катализатор Циглера – Натта</kwd><kwd>титан-магниевый катализатор (ТМК)</kwd><kwd>гельпроникающая хроматография (ГПХ)</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polyhexene</kwd><kwd>molecular mass</kwd><kwd>molecular mass distribution</kwd><kwd>Ziegler-Natta catalyst</kwd><kwd>titanium-magnesium catalyst (TMC)</kwd><kwd>gelpermation chromatography (GPC)</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Chien J.C.W., Gong B.M. // J.
