Description

一种催化环氧烷烃开环聚合生成聚醚的方法
技术领域
本发明涉及一种催化环氧烷烃开环聚合生成聚醚的方法,属于聚醚多元醇合成技术领域,具体涉及环氧烷烃开环聚合的有机路易斯酸碱对体系,聚合工艺及双官能化封端聚醚多元醇的方法。
背景技术
聚醚多元醇制得的聚氨酯弹性体具有较好的水解稳定性、耐候性、低温柔顺性和耐霉菌等性能广泛应用于汽车配件、电缆、薄膜、医疗器材、胶辗、耐油密封件等方面。聚环氧丙烷(PPO)是聚醚多元醇家族的重要成员,在许多应用中用作润滑剂、洗涤剂、印刷油墨、表面活性剂、化妆品试剂和泡沫控制剂的关键成分,主要以低聚物的形式用于上述领域或作为聚氨酯的前体。
现有制备聚醚多元醇的方法通常包括在碱催化剂和双金属络合催化剂催化聚合,聚合反应得到的粗聚醚多元醇大多含有金属离子、副反应产生的醛、低分子量聚合物以及未反应的氧化烯烃等物质,使得聚醚多元醇存在色度异常或容易产生刺激性气味的问题,因此需要对聚醚多元醇进行后处理。此外,上述聚合反应温度较高,一般为100~150℃。因此,提供一种可以在温和的条件下催化环氧烷烃开环聚合生成聚醚的反应,高效地制备得到分子量高、分子量分布窄且不含金属元素的聚醚多元醇聚合物是十分必要的。
发明内容
本发明为了解决上述现有聚醚多元醇制备方法存在的技术问题,提供一种催化环氧烷烃开环聚合生成聚醚的方法。

更进一步限定,环氧烷烃为PO(环氧丙烷)、BO(环氧丁烷)、AGE(烯丙基缩水甘油醚)、EO(环氧乙烷)中一种或几种混合。
进一步限定,路易斯酸为三乙基硼。
进一步限定,路易斯碱、路易斯酸、引发剂和环氧烷烃的摩尔比为(0.05~1):(0.15~3):(0~5):(100~1000)。
进一步限定,聚合温度为40~60℃,反应时间为4~51h。
本发明的目的之二是提供上述方法中使用的路易斯碱的制备方法,该方法为:合成路易斯碱的原料由摩尔比为(1~2):2:1的吡啶盐、双(三甲基硅烷基)氨基钾和二异丙基氯化膦组成。
进一步限定,吡啶盐结构式如下:

Figure BDA0003811125600000031
本发明提供的一种催化环氧烷烃开环聚合生成聚醚的方法,该聚合反应采用非金属体系吡啶有机磷催化剂在相对温和的条件下(40~60℃),实现双羟基封端的聚醚多元醇的制备。与现有技术相比本申请还具有以下有益效果:

(3)本发明使用吡啶有机磷作为催化剂制备聚合物时,可在双羟基引发剂存在的情况下进行,因此可以调控制备聚合物的分子量,降低催化剂的用量,降低聚合物的分子量分布,制备带有双羟基末端官能团的双羟基聚醚多元醇。
(4)本发明制备得到的聚合物分子量可控(950~14300g/mol),分子量分布窄(
