PROCESSES TO PREPARE ETHYLENE-BASED POLYMER COMPOSITIONS |
| 摘要 |
<p>The present invention relates to a process to form an ethylene-based polymer composition, the process comprising at least the following:
Step 1: polymerizing a first ethylene-based polymer in the presence of at least one molecular catalyst and a hydrocarbon chain transfer agent, and at a polymerization pressure of at least 14,000 psi;
Step 2: polymerizing a second ethylene-based polymer</p> |
