MODIFIZIERUNG VON MIT EINEM ZIEGLER- ODER SINGLE- SITE-KATALYSATOR HEREGESTELLTEM POLYETHYLEN MIT EINEM RADIKALBILDENDEN INITIATOR |
摘要 |
<p>A method of modifying a polyethylene is disclosed. In the method ethylene or a mixture of ethylene and a C3-C10 alpha-olefin is polymerized in an organic solvent with a Ziegler or single-site catalyst to form an initial polyethylene solution. The initial polyethylene solution is then reacted with a free radical initiator to produce a modified polyethylene. The modified polymer has an enhanced melt elasticity and increased long chain branching index, and is essentially free of gel.</p> |
