| titleOfInvention | Improved process for gas-phase polymerization having high polymer bed bulk density |
| abstract | The present invention is directed to an improvement for a gaseous olefin polymerization process having a relatively high polymer layer bulk density. The improvement comprises the use of a mixed external electron donor when polymerizing propylene in a gas phase reactor having a bulk density of greater than 128 kg / m < 3 > and optionally including a polymer layer having at least one comonomer, The electron donor system comprises at least one first external electron donor and one second external electron donor, wherein the first external electron donor is a carboxylate compound. |
