PROCESSES TO PREPARE ETHYLENE-BASED POLYMER COMPOSITIONS

摘要

The invention provides 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.
