PROCESS TO MAKE LONG CHAIN BRANCHED (LCB), BLOCK, OR INTERCONNECTED COPOLYMERS OF ETHYLENE |
摘要 |
A process is taught, comprising polymerizing ethylene in the presence of a catalyst to form a crystalline ethylene-based polymer having a crystallinity of at least 50% as determined by DSC Crystallinity in a first reactor or a first part of a multi-part reactor and reacting the crystalline ethylene-based polymer with additional ethylene in the presence of a free-radical initiator to form an ethylenic polymer in at least one other reactor or a later part of a multi-part reactor.
