研究了新型均光敏聚合物和共光敏聚合物的光反应性，这些聚合物含有通过光敏基团和主链之间的间隔基长度连接的侧链查耳酮部分。在不同的溶液条件下，如：主链结构，共聚，不同的溶剂，不同的浓度和不同的温度下，所制备的聚合物的交联速率进行了研究。所制备的单体和聚合物的结构通过不同的光谱方法和元素分析进行了确认。通过凝胶渗透色谱法测定聚合物的平均分子量。聚合物的热稳定性通过热重分析在氮气气氛下测量。
The photoreactivity of new homo- and co-photosensitive polymers containing pendant chalcone moieties attached through hexamethylene spacer lengths between the photosensitive group and the backbone were studied. The rates of crosslinking of the prepared polymers were investigated under different conditions in solutions such as: backbone structures, copolymerization, different solvents, different concentrations and different temperatures. The structures of the prepared monomer and polymers were confirmed by different spectroscopic methods and elemental microanalysis. The average molecular weights of the polymers were determined by gel permeation chromatography. The thermal stability of the polymers was measured by thermogravimetric analysis under a nitrogen atmosphere.
