以丙三醇或水为共引发剂，三氟化硼乙醚(BF3?OEt2)为引发剂，引发四氢呋喃阳离子开环聚合，合成了一种新型聚四氢呋喃三元醇(PTHF-T)及聚四氢呋喃二元醇(PTMG/PTHF-D)。研究了丙三醇、丙三醇/水、水、反应时间等对聚合反应的影响。用傅里叶变换红外光谱法(FTIR)表征PTHF结构，凝胶渗透色谱法(GPC)、黏度法测定分子量，端基滴定法测定羟值。结果表明，不同丙三醇/水比例，可定量获得不同官能度的聚四氢呋喃多元醇(PTHF)；丙三醇为共引发剂能得到产率高且分子量分布窄的PTHF；同时得出PTHF重均分子量Mw与黏均分子量Mη的关系式。该PTHF-T可用于聚氨酯快速吸附材料的制备。

Ring-open polymerization of tetrahydrofuran (THF) was investigated with glycerin or water as co-initiator, boron (tri) fluoride etherate (BF3·OEt2) as initiator, and a new type of polytetrahydrofuran triol (PTHF-T) and polytetrahydrofuran glycol (PTMG or PTHF-G) was synthethized. The factors that affect polymerization reaction, such as the amounts of glycerin, glycerin and water, water, reaction time, were discussed. The polymers were characterized by Fourier Transform Infrared Spectrometry (FTIR), gel permeation chromatography (GPC), viscosimetry, hydroxyl value. The degree of functionalization of PTHF varied linearly with the relative glycerin content in glycerin-water mixture. PTHF triol with a narrow molecular weight distribution and a higher yield was obtained when glycerin was used as co-initiator. The relationship between GPC and viscosimetry was obtained. Polytetrahydrofuran triol (PTHF-T) was used in the preparation of polyurethane rapid adsorption material.
