本文用红外光谱法研究了大孔交联聚丙烯醛及其含氮衍生物树脂的结构;考察了交联聚丙烯醛树脂交联度与醛基、醚键相对含量之间的关系;用醛基含量的减小值来计算聚丙烯醛与氨的衍生物反应的反应程度。
In this paper, the structure of macroporous crosslinked polyacrolein and its nitrogen-containing resin was studied by infrared spectroscopy. The relationship between the degree of crosslinking of crosslinked polyacrylic resin and the relative content of aldehyde groups and ether bonds was investigated. The reduction of the base content is used to calculate the degree of reaction of the reaction of the polyacrylaldehyde with the ammonia derivative.
