Progress of Non-metallocene Catalysts for Olefin Living Polymerization
摘要/Abstract
阐述了近些年来非茂金属烯烃活性聚合催化剂的研究进展及其应用.讨论了它们的合成、结构及其对催化烯烃聚合活性的影响,考察了不同杂原子和取代基对催化烯烃聚合活性、聚合物结构和分子量大小的影响.研究表明:非茂类金属化合物制备方便,反应条件温和,在催化烯烃聚合中表现出了较高的催化活性.
The prog ress in the research and application of non-metallocene catalysts for olefin living polymerization has been reviewed in recent years.Their synthesis,molecular structure and reactivity for olefin polymerization are discussed.The impact of different heteroatom and subst ituents on the catalytic olef in polymerization act ivity,the structure and molecular weight of polymer are invest igated.Research shows that the preparation for non-metallocene is convenient and the reaction conditions are mild.They show high cataly tic activity in the olef in polymerization.
