摘要
以过氧化二苯甲酰 (BPO)为引发剂 ,采用本体聚合方法制备了聚 4 乙烯基吡啶 (P4VP) ,然后用冰醋酸为溶剂 ,钨酸钠为催化剂 ,过氧化氢为氧化剂 ,氧化聚 4 乙烯基吡啶合成了聚 4 乙烯基吡啶氮氧化物 (PVNO) ,探讨了反应条件对PVNO特性粘数的影响。另外 ,采用TG
In this paper,first the poly-4-vinylpyridine was made by bulk polymerization with BPO as initiator, then oxygenated poly-4-vinylpyridine was oxidized to poly-4-vinylpyridine-N-oxide in solvent of glacial acetic acid with catalyst of Na_2WO_4 and oxidant of thirty percent of hydroperoxide. The effect of reaction conditions on intrinsic viscosity was discussed. Otherwise,to characterize the PVNO TG-DTA have been used.
