PROCESS FOR THE PREPARATION OF POLYMER OF 1-BUTENE |
摘要 |
<p>A process for the preparation of 1-butene homopolymers or 1-butene/alpha olefin copolymers wherein the alpha olefins are selected from ethylene, propylene or alpha olefins of formula CH2═CHZ wherein Z is a C3-C20 alkyl radical, comprising contacting 1-butene or 1-butene and one or more alpha olefins under polymerization conditions in the presence of a catalyst system comprising: (a) a solid component comprising a Ti compound and an internal electron-donor compound supported on MgCl2 (b) an alkylaluminum cocatalyst; and (c) a compound of formula (I) as external donor</p> |
