| Abstract: | The progress in preparation of linear low density polyethylene by tandem catalysis of ethylene was reviewed.According to the type of catalyse,the catalytic systems of oligomerization catalyst/copolymerization catalyst/cocatalyst and catalyst/oligomerization cocatalyst/copolymerization cocatalyst were introduced respectively.According to the difference in catalyst,the catalyst combination were classified.Properties of these catalytic systems and polymer obtained were stated emphatically. |
