Polymerization process for production of polymer |
| 摘要 |
A process comprising contacting a catalyst system with one or more olefins in a bubble column reactor. Also, a polyolefin copolymer composition comprising ethylene, propylene and optionally a C4 to C20 alpha olefin; said composition having a bimodal distribution with respect to composition distribution, molecular weight distribution or a combination thereof; an Mw of 10,000 g/mol or more; and/or at least two melting peaks in a DSC heating cycle with a difference in melting temperatures of at least 5° C. |
