Description

一种含苯基酸酐类-环氧乙烷四元共聚物
本申请要求于2021年09月24日提交中国专利局、申请号为CN202111125717.5、发明名称为“一种含苯基酸酐类-环氧乙烷四元共聚物”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明属于IPC分类号C08G64/18技术领域,具体涉及一种含苯基酸酐类-环氧乙烷四元共聚物。
背景技术
随着环保要求越来越严格,聚乙烯、聚丙烯等传统塑料材料因为难以降解,废弃后进入环境造成了严重的“白色污染”,逐渐降低了其单独作为环保材料的应用价值。现阶段,开发生物可降解性能较好的塑料材料是十分有必要的。二氧化碳的过量排放已引起了明显的全球气候变暖,回收、利用二氧化碳对减少碳排放,进而改善气候条件有重要意义。
环氧丙烷与二氧化碳共聚生成的聚甲基乙撑碳酸酯(PPC)是一种透明的、完全可降解的环保型塑料,其断裂拉伸应变为600~1200%,但是其玻璃化温度较低(Tg=30~40℃)。公开号为CN111378101A的中国发明专利公开了一种环氧丙烷、邻苯二甲酸酐、二氧化碳的三元共聚物能在PPC的基础上提高玻璃化温度(Tg=40~50℃),但是由于二氧化碳活性较低,引发反应很慢,反应时间长,增加了能耗。并且,环氧丙烷-邻苯二甲酸酐-二氧化碳三元共聚物的熔体质量流动速率(MFR)太高,难以在高温下、稳定地加工。为了进一步优化制备得到的共聚物的性能,并且保证反应的可操作性和减少能耗,开发一种新的共聚物仍是一项重要的任务和挑战。
发明内容
为了解决上述技术问题,本发明的第一方面提供了一种含苯基酸酐类-环氧乙烷四元共聚物,制备原料包括共聚物单体和催化剂;
所述的共聚物单体包括环氧乙烷、环氧丙烷、含苯基酸酐类和二氧化碳。
优选的,所述的环氧乙烷的重量为共聚物总重量的15~40wt%。
本发明发现,加入环氧乙烷后可以大大改善共聚物的制备活性,尤其在环氧乙烷的重量为共聚物总重量的15~40wt%时,可以保证制备得到四元共聚物具有较好的韧性,出现这种现象的原因可能是:在反应过程中,随着环氧乙烷的加入,在体系中生产活性-OH,促进体系中含苯基酸酐类物质和环氧乙烷之间的开环聚合反应,同时,促进了分子间的相互作用的强度和增强了分子链间相互依附能力,提升了其面对外力作用时在分子链段间形成快速的分散和转移,避免局部的应力集中现象出现,因此,提升了制备得到的材料的韧性。
优选的,所述的含苯基酸酐类选自邻苯二甲酸酐、苯基琥珀酸酐、对甲苯甲酸酐、苯氧基乙酸酐、2-苯基丁酸酐和甲基四氢邻苯二甲酸酐中的至少一种。
进一步优选的,所述的含苯基酸酐类为邻苯二甲酸酐。
优选的,所述的催化剂为含硼化合物和/或烷基卤化铵。
优选的,所述的催化剂为含硼化合物和烷基卤化铵。
优选的,所述的含硼化合物和烷基卤化铵的摩尔比为(1~10):1。
进一步优选的,所述的含硼化合物和烷基卤化铵的摩尔比为(1~6):1。
进一步优选的,所述的含硼化合物和烷基卤化铵的摩尔比为2.5:1。
进一步优选的,所述的三乙基硼和四正丁基溴化铵的摩尔比为5.35:1;
进一步优选的,所述的三乙基硼和四正丁基溴化铵的摩尔比为1:1;
本发明发现,在本体系中选择以含硼化合物和烷基卤化铵作为催化剂,尤其在其摩尔比为(1~6):1的条件下,可以避免体系中出现聚合物间的副反应发生,避免出现杂链,并且可以保证制备得到的共聚物的熔体流动速率得到大大改善,可以保证其在160℃下的容易流动速率在20g/10min以下,低至3.7g/10min,保证了经本发明制备得到的含苯基酸酐类-环氧乙烷四元共聚物在吹塑产品制备的可能性。
另外,本发明发现,在本体系中,当加入的含硼化合物和烷基卤化铵摩尔比大于6以后,会造成其自身发生自氧化作用,而导致其催化效果降低,进而影响共聚物的制备。
优选的,所述的含硼化合物选自三乙基硼和三丁基硼中的一种。
优选的,所述的含硼化合物为三乙基硼;所述的三乙基硼以溶液的形式加入,所述溶液为三乙基硼四氢呋喃溶液,溶液的摩尔浓度为1mol/L。
优选的,所述的烷基卤化铵选自四正丁基氟化铵、四正丁基氯化铵、四正丁基溴化铵、四正丁基碘化铵、四正丙基氟化铵、四正丙基氯化铵、四正丙基溴化铵和四正丙基碘化铵中的至少一种。
优选的,所述的含硼化合物和含苯基酸酐类的摩尔比为1:(10~500)。
进一步优选的,所述的含硼化合物和含苯基酸酐类的摩尔比为1:(10~500)。
进一步优选的,所述的含硼化合物和含苯基酸酐类的摩尔比为1:(80~200)。
优选的,所述的环氧乙烷和含苯基酸酐类的摩尔比为1:(2~20)。
进一步优选的,所述的环氧乙烷和含苯基酸酐类的摩尔比为(2~20):1。
进一步优选的,所述的环氧乙烷和含苯基酸酐类的摩尔比为(3~12):1。
本发明发现,在本体系中,选择加入环氧乙烷并且保证其与含苯基酸酐类物质的摩尔比为(3~12):1时,可以大大改善制备得到的共聚物为嵌段共聚物,并且可以保证大大提升反应活性,降低反应过程中的能耗,保证制备的材料具有较好的力学性能和生物降解性能的同时还能提升经济效益和应用价值,出现这种现象的原因可能是:在本体系中,控制环氧乙烷和含苯基酸酐类的摩尔比为(3~12):1时,体系中的环氧乙烷会吸附在三乙基硼和烷基卤化铵的表面,使碳碳单键的电子云密度偏向外侧,有利于含苯基酸酐类物质在电子云密度的作用下发生加成反应,促进共聚物链长的增长,同时,在环氧乙烷和含苯基酸酐类的复配下,可以平衡共聚物分子中软链段和硬链段的含量,进而保证了制备材料的较好的力学性能。
优选的,共聚物为无规则结构或嵌段结构;
无规则结构包括式(1)、式(2)、式(3)、式(4)、式(5)、式(6)、式(7)和式(8)中的一种:
