| 摘 要： | <正> 关于四氢呋喃(THF)活性聚合的研究文献上已有较多报道,而对共聚合的“活”性行为则研究甚少。THF与环氧丙烷(PO)共聚合时副反应较多,如生成环聚体、异构化等。这是否影响链的“活”性,是饶有兴趣的问题。特别是THF均聚醚在分子

| Abstract: | The living chains were obtained in the bulk tetrahydrofuran (THF)-propylene oxide (PO) (10-20 wt. %) copolymerization initiated by adipoyl chloride (AC)-AgC104(AC]0=0.02-0.09mol.l-1) catalyst at -10-0℃ without chain termination and transfer reactions. Estimation of reactivity ratios yielded values of 0.8 ?.2 and 0.08 + 0.03 for THF and PO, respectively. The functionality of living chains with 10% PO in feed is close to 2. Four different telechelic THF-PO eopolymers with amino or hydroxyl end-groups P(THF-co-PO)R, where R=-NHBu,-NHPh, -NEt2 or-OH] were synthesized. |
