研究了一种测定聚丙烯酸甲酯上酰肼基团分布的新方法。将功能化的聚丙烯酸甲酯类树脂上的酰肼基团与Cu2 +络合 ,利用X射线能谱微区分析对树脂上Cu2 +的存在部位及分布进行分析 ,从而确定树脂上酰肼基团的存在部位及分布情况。结果表明:在交联度及其他成分相同时 ,树脂表面及断面的酰肼化程度有很大差异。
A new method to determine the distribution of hydrazide groups on poly (methyl acrylate) was studied. The hydrazide groups on the functionalized poly (methyl acrylate) resin were complexed with Cu2 +, and the presence and distribution of Cu2 + on the resin were analyzed by X-ray EDM. Mission of the existence of parts and distribution. The results show that there are great differences in the degree of hydrazide on the surface and cross section of the resin when the degree of crosslinking and other components are the same.
