本文用聚丙烯酸十四醇酯(分级和未分级)对文献报导求聚合物平均分子量的处理法作比较,发现其中Mahabadi方法和取α=0.74的结果较好,且还可同时获得体系的α值. In this paper, tetradecyl acrylate (graded and non-graded) compared to the reported method for calculating the average molecular weight of the polymer, Mahabadi method and the results obtained with α = 0.74 is better, and can also be obtained at the same time α value.
