Catalysts for the polymerization of olefins |
| 摘要 |
The present invention relates to catalysts particularly suitable for the sterospecific polymermerization of olefins, comprising Ti, Mg, halogen and an electron donor compound selected from heteroatoms containing esters of malonic acids. Polymers produced by the catalysts have high isotactic index expressed in terms of high xylene insolubility.
