中间相沥青分子量分布的测定

DETERMINATION OF MOLECULAR WEIGHT DISTRIBUTION OF MESOPHASE PITCH

通过对中间相沥青进行还原、烷基化增溶处理,使之完全溶于测试溶剂四氢呋喃,测定了中间相沥青的平均分子量,并采用宽分布校正方法,确定了中间沥青的分子量分布。

Solubilized by reductive alkylation, mesophase pitch could be dissolved in THF completely, therefore, average molecular weight and MWD were determined with wide-distribution calibration curve.
