| Abstract: | Advances in preparation of linear low-density polyethylene(LLDPE)by in situ copolymerization of ethylene during recent 20 years were reviewed.In respect of difference in copolymerization catalysts,three kinds of difunctional catalyst systems used for preparation of LLDPE,namely Ziegler-Natta catalyst system,metallocene catalyst system and non-metallocene catalysts system,were mainly introduced.Properties of these catalyst systems and polymer obtained were also included. |

| Keywords: | in situ copolymerization linear low-density polyethylene Ziegler-Natta metallocene difunctional catalyst system catalyst |
