注解：
Mn Number average molecular weight
Mp Peak average molecular weight
Mv Viscosity average molecular weight
Mw Weight average molecular weight
Mz Z-average molecular weight
IV* Intrinsic Viscosity (dl/gm)
数均分子量（Number-average molecular weight）：按聚合物中含有的分子数目统计平均的分子量，高分子样品中所有分子的总重量除以其分子(摩尔)总数。
重均分子量（ Weight-average molecular weight）：按照聚合物的重量进行统计平均的分子量，i-聚体的分子量乘以其重量分数的加和。
Z均分子量（Z-average molecular weight ）：按照Z值统计平均的分子量
粘均分子量（Viscosity- average molecular weight）：对于一定的聚合物－溶剂体系，其特性粘数[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，即低分子量部分对Mn影响较大
Mw靠近聚合物中高分子量的部分，即高分子量部分对Mw影响较大
一般用Mw来表征聚合物比Mn更恰当，因为聚合物的性能如强度、熔体粘度更多地依赖于样品中较大的分子。
