含砜功能基的交联聚苯乙烯的红外光谱特性

INFRARED SPECTRUM FEATURE OF THE SULFONYL GROUP BOUND TO CROSSLINKED POLYSTYRENES

本文合成了一系列聚苯乙烯基支载的含砜基的化合物X=Cl,O(CH_2)_9CH_3,NH_2,NHNH_2,Na,CH_2CH_3,OH)并较系统地研究了这些聚合物中的=SO_2基团的红外光谱特性,比较了聚合物和低分子类似物的特征吸收频率的变化规律,考察了聚合物骨架对S=O基团的虹外吸收峰的影响。

Crosslinked polystyrenes containing subst tuted sulfonyl groups (RSO2 X:X = Cl, O(CH2)9 CH3, NH2, NHNH2, Na, CH2CH3 and OH; R =polystyryl) were prepared. The 1R spectra of these compounds were assigned and compared with that of polystyrene and small molecular analogues. The characteristic absorption bands of the> SO2 group bound to the polymers and the effect of the polymer backbone on the IR spectra were discussed.
