IV* - Instrinsic Viscosity in 0.05M Sodium Sulfate at 30°C
分子量参数注解:
Mw -- Weight average molecular weight / 重均分子量: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。
Mn -- Number average molecular weight/ 数均分子量: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。
Mp -- Peak average molecular weight / 峰值分子量
Mv -- Viscosity average molecular weight / 粘均分子量:对于一定的聚合物-溶剂体系,其特性粘数[η]不同。
Mz -- Z-average molecular weight / Z均分子量:按照Z值统计平均的分子量。
IV* -- Intrinsic Viscosity (dl/gm) /固有粘度
