摘要

本综述介绍了茂金属催化剂的分子结构对茂金属聚

-烯烃(mPAO)合成基础油分子结构(立构规整性、区域规整性、分子量等)的调控机制，并归纳了mPAO基础油分子结构与其性能间的内在联系. 重点阐述了支链长度、支链数量、分子量及立体化学属性等关键结构参数对mPAO的黏度、黏度指数、倾点、结晶性、剪切稳定性及摩擦性能的影响规律. 对mPAO构效关系的理解不仅有助于完善润滑油领域的基础理论体系，更为高性能润滑油产品的设计与开发提供了重要的理论依据和支撑.

Abstract

This review comprehensively investigates how the molecular structures of metallocene catalysts govern the molecular structures of polyalphaolefins (PAOs)

focusing on stereoregularity

regioregularity

and molecular weight. It also elucidates the critical relationship between PAO molecular structures and their performance properties. Specifically

it analyzes how key molecular parameters—including branch length

branch number

molecular weight

and stereochemistry—influence essential performance of base oil such as viscosity

viscosity index

pour point

crystallizability

shear stability

and tribological behavior. By synthesizing these structure-property-performance relationships

this article establishes a systematic framework for understanding the mPAO-based lubricants and serves as a foundational reference for developing high-performance mPAO-based lubricants.
