HOMOPOLYMERS AND COPOLYMERS OF ETHYLENE |
摘要 |
Ethylene homopolymers and copolymers having a broad molecular distribution, excellent toughness and improved processability are disclosed. These polymers may be prepared by use of a single metallocene catalyst system in a single reactor in the gas phase. These polymers of density typically 0.85-0.95 are defined in particular by their melt strength (MS) and long chain branching (LCB) characteristics and are particularly suitable for use in low density film applications.
