| 摘要 |
<p>The invention concerns a method for polymerising alpha-olefins which consists in contacting, in polymerising conditions, at least an alpha-olefin with a catalytic system comprising: (a) a catalytic complex based on a transition metal (M) of groups 6 to 12; (b) an aluminoxane; and (c) a boroxine represented by formula (I) wherein R1 to R3 represent each, independently, an alkyl, cycloalkyl, alkoxy or aryl group, optionally substituted.</p> |
