PROCESS FOR PRODUCTION OF PROPYLENE COPOLYMERS |
摘要 |
The properties and the amounts of polymers produced in the second stage of a polymerization process in the presence of propylene and ethylene or other alpha olefin are controlled by the addition of an external electron donor to the second stage polymerization. The dosage of external donor to the second stage polymerization is based on a percentage of the dosage of external donor to a first stage polymerization of propylene in the process. The external donor added to the second stage is either the same as or different from the external donor added to the first stage.
