COMPONENTS OF CATALYSTS FOR POLYMERIZING ALPHA-OLEFINS AND THE CATALYSTS FORMED FROM THE COMPONENTS |
| 摘要 |
<p>New components of catalysts for polymerizing alphaolefins, and the catalysts formed from the new components are disclosed. Said catalyst components are prepared by reacting Ti compounds with a carrier in the form of spheroidal particles of specified characteristics and which consists of or comprises an Mg compound, or mixture of Mg compounds of the formula XNMG(OR)2-N (I) in which O<N<2, R is an alkyl, aryl, cycloalkyl radical containing from 1 to 20 carbon atoms X is halogen or a group OR" in which R" is an alkyl, aryl or cycloalkyl radical containing from 1 to 20 carbon atoms and is the same or different from R in formula (I).</p> |
