烷基铝对乙烯聚合活性及分子质量分布影响的研究

Effect of polymer's activity and molecular weight distribution on alkylaluminum

介绍了烷基铝作为主要的烯烃聚合助催化剂的研究现状,分析了烷基铝对乙烯聚合活性及分子质量分布的影响规律,简述了目前生产中常用的聚合物分子质量调整办法,以及辽阳石化的氯化聚乙烯专用料产品进行分子质量分布调节的必要性和意义。

Current situation of alkylaluminum as co- catalyst of olefin＇s polymer was indroduced. Effect on polymer＇s activity and molecular weight distribution by alkylaluminum was also analyzed. Methods of adjusting polymer molecular weight distribution at present were reviewed, and necessity and significance of chlorinated polyethylene products of Research Institute of Liaoyang Petrochemical Company on method of adjusting polymer molecular weight distribution was also inferred.
