| titleOfInvention | Two-phase method for producing polypropene composition |
| abstract | A kind of method of the polypropylene in the presence of polymerization catalyst, it is by two polymerization stages, by propylene and comonomer combined polymerization, and the comonomer selects the group that free ethylene and C4 C10 alhpa olefins are constituted.First polymerization stage is carried out in circulation flow reactor, and the second polymerization stage is carried out in Gas-phase reactor.Polymer produced in first polymerization stage is compared to final polymeric blends, the content with higher melt flow rate (MFR) and lower comonomer unit.Methods described can be operated under high-throughput and catalyst productivity. |
