4‐isopropenyl phenyl glycidyl ether (IPGE). On further reaction with carbon dioxide in the presence of tetra‐n‐butyl ammonium bromide (TBAB) as the catalyst, IPGE was transformed into 4‐isopropenylphenoxy propylene carbonate (IPPC) in 90% yield. Cationic polymerization of IPPC with strong acid such as trifluoromethanesulfonic acid or boron trifluoride diethyl etherate as the catalyst at −40 °C gave a linear po
4-异丙烯基苯酚(4-IPP)是一种通用的双功能中间体,可以很容易地从双酚A(BPA)制备。通过用环氧氯丙烷醚化成4- IPP的酚基,可以将其转化为4-异丙烯基苯基缩水甘油醚(IPGE)。在四正丁基溴化铵(TBAB)作为催化剂存在下与二氧化碳进一步反应后,IPGE以90%的产率转化为4-异丙烯基苯氧基碳酸亚丙酯(IPPC)。IPPC的阳离子聚合用强酸(例如三氟甲磺酸或三氟化硼二乙醚)作为催化剂在-40°C下得到线性聚(异丙烯基苯氧基碳酸亚丙酯),即聚(IPPC),其中多环碳酸酯基团在聚合物的侧链上被均匀取代。聚(IPPC)的环状碳酸酯基团进一步与不同的脂肪胺和二胺反应,形成侧链上带有羟基聚氨酯的聚合物。介绍了聚(IPPC)的合成,表征及其向羟基-聚氨酯交联聚合物的转化。©2015 Wiley Periodicals,Inc.
