iv* - intrinsicviscosity in thf at 30°c
mark-houwinkparameters: a = 0.69; k = 0.000128
分子量参数注解：
mw -- weight average molecularweight / 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 molecularweight/ 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 molecularweight / 峰值分子量
mv -- viscosity average molecularweight / 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
