阴离子聚合PA6与苎麻纤维复合反应中的阻聚与变色机理的研究

Abstract:
通过浇注成型的方法研究并发现了苎麻纤维与阴离子聚合尼龙6（APA-6）反应加工过程中严重的阻聚和变色问题.为了分析阻聚和变色的机理并寻找解决方案，选取了3种不同的引发剂（氢氧化钠、己内酰胺钠盐和己内酰胺溴化镁）分别与微晶纤维素（MCC）在150℃的真空条件下反应.然后分别采用傅里叶变换红外光谱、原子吸收光谱、X-射线衍射和核磁共振波谱表征了引发剂和MCC反应前后的变化.结果证明，阻聚和变色的机理是在强碱性和高温条件下，纤维素发生了剥皮反应，产生的副产物又极易与引发剂反应，因此导致APA-6中起引发作用的己内酰胺阴离子被消耗，从而使得聚合反应终止.另外，由于己内酰胺溴化镁（C1）的低活性和弱碱性，使得剥皮反应很大程度的降低，进而避免了引发剂阴离子的消耗，从而使得阻聚和变色问题得到明显改善，最终实现了通过反应加工的方法制备APA-6与苎麻纤维复合材料的目的.
