Process for the preparation of propylene polymers |
| abstract |
The present invention concerns a propylene polymerization process comprising preactivating the catalyst in the presence of cocatalyst and external donor, preferably activating the preactivated catalyst by a cocatalyst and further possibly prepolymerizing the obtained catalyst and polymerizing propylene optionally together with other comonomers without adding any additional external donor after the preactivating step. |
