摘要
介绍了易加工线型低密度聚乙烯(LLDPE)的性能特点。综述了制备易加工LLDPE的方法,包括:通过设计聚合催化剂生成具有长支链结构的LLDPE;通过控制聚合工艺或催化剂形成双峰或宽峰分布的LLDPE;通过后加工改性改善LLDPE的加工性能等。
This paper introduced the features of easy-processing linear low density polyethylene（LLDPE）, and reviewed its production technologies, such as preparation of long-chain branching LLDPE with the specially designed polymerization catalysts, synthesis of LLDPE with bimodal or broad relative molecular mass distribution via control of polymerization technology or catalyst and improving processability of LLDPE with post-processing modification, etc.
