數(shù)均分子量（Number-average molecular weight）：按聚合物中含有的分子數(shù)目統(tǒng)計(jì)平均的分子量，高分子樣品中所有分子的總重量除以其分子(摩爾)總數(shù)。
重均分子量（ Weight-average molecular weight）：按照聚合物的重量進(jìn)行統(tǒng)計(jì)平均的分子量，i-聚體的分子量乘以其重量分?jǐn)?shù)的加和。
Z均分子量（Z-average molecular weight ）：按照Z(yǔ)值統(tǒng)計(jì)平均的分子量
粘均分子量（Viscosity- average molecular weight）：對(duì)于一定的聚合物－溶劑體系，其特性粘數(shù)[η]不同。
Mz > Mw > Mv > Mn，Mv略低于Mw
Mn靠近聚合物中低分子量的部分，即低分子量部分對(duì)Mn影響較大
Mw靠近聚合物中高分子量的部分，即高分子量部分對(duì)Mw影響較大
一般用Mw來(lái)表征聚合物比Mn更恰當(dāng)，因?yàn)榫酆衔锏男阅苋鐝?qiáng)度、熔體粘度更多地依賴(lài)于樣品中較大的分子。
