1-OLEFIN STEREOBLOCK POLYMER WAX,AND A PROCESS FOR THE PREPARATION THEREOF |
| 摘要 |
1-olefin stereoblock polymer waxes having a very narrow molecular weight distribution are obtained by means of a catalyst which comprises an aluminoxane and a metallocene compound containing cyclopentadienyl radicals which are substituted by chiral groups, in the presence of small amounts of nitrogen during the polymerisation. |
