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
