采用高氯酸/乙酸酐引发四氢呋喃阳离子开环聚合制备出聚四氢呋喃，并用均匀设计法研究了各工艺参数的影响，通过多元逐步回归的方法对结果进行分析得到聚四氢呋喃产物相对分子质量的预测方程，同时评价了聚合过程中高氯酸加入量、乙酸酐加入量及聚合时间对产物相对分子质量和相对分子质量分布的影响。研究发现，在选取的研究范围内，乙酸酐加入量、高氯酸加入量和聚合时间对聚四氢呋喃产物相对分子质量影响的显著性依次降低，其中聚合时间的影响可以忽略；聚四氢呋喃的相对分子质量分布则几乎不受工艺参数的影响。

Polytetrahydrofuran (PTHF) was synthesized by cationic ring-opening polymerization of THF initiated by HClO4/acetic anhydride. The effects of polymerization parameters,such as adding amount of HClO4,acetic anhydride,and polymerization time,on the molecular weight and molecular weight distribution of PTHF were studied with uniform design. Relevant data were analyzed by multiple stepwise regression. The significance of adding amounts of acetic anhydride,HClO4 and polymerization time on molecular weight of PTHF reduced in sequence,with negligible influence of polymerization time. At the same time,molecular weight distribution of PTHF could not be affected by technological parameters.
