- Аннотация: The syndiospecific polymerization of styrene is studied in the presence of titanium complexes with dialkanolamines-bistitanocanes and titanocane-activated by individual MAO or the combined cocatalyst MAO/TIBA. It is shown that these catalysts are more active and stereospecific after their activation with the combined cocatalyst ([TIBA]: [MAO] a parts per thousand currency sign 0.13) than that in the case of the activation with MAO: The activities of the catalysts are a parts per thousand currency sign18 and 9 kg PS/(mol Ti h), and the syndiotacticities of PS are a parts per thousand currency sign76 and 60%, respectively. Polymers synthesized in the presence of bistitanocanes are characterized by M (n) a parts per thousand currency sign 4.5 x 10(4) and T (m) a parts per thousand currency sign 268A degrees C and a narrow molecular-mass distribution (a parts per thousand currency sign2.5).
