samples provided reactivity parameters ∆Hp, Rp,max and tmax, while FTIR spectra before and after curing elucidated the underlying polymerization mechanism. Mechanical testing of the obtained polymers exhibited gradual differences in network densities, depending on the intramolecular arrangement and number of functional groups. Overall, a general building principle for highly reactive, liquid diacrylamides
通过两步合成,制备了六个可聚合的N,N'-二酰基酰胺,它们包含空间排列的N-丙烯酰基,N-烯丙基和/或N-烷基,并通过1H / 13C NMR光谱,折射率(RI)和粘度测量进行了表征。活化样品的光DSC测量提供了反应性参数∆Hp,Rp,max和tmax,而固化前后的FTIR光谱阐明了潜在的聚合机理。对获得的聚合物的机械测试显示出网络密度的逐渐差异,这取决于分子内的排列和官能团的数量。总体而言,可以确定通过最佳排列的官能团的协同组合来制备高反应性液态二丙烯酰胺的一般方法。对于低粘性N,N',发现了分子内协同作用的最高水平
