摘要
采用悬浮聚合法,以顺丁烯二酸酐为交联剂,添加硅藻土,制得硅藻土-聚乙烯醇高吸水性树脂。该树脂的吸水倍率为357倍。探讨了交联剂用量、硅藻土添加量、水解程度等因素对树脂吸水性能的影响。
A PVA superabsorbent composite resin containing diatomite was synthesized by suspension polymeriza tion using maleic anhydride as cross-linking agent. The water absorbency of the resin were 357g · g^-1. By a series of experiments, the influence of the amount of crosslinking agent, diatomite and of hydrolysis degree on water absorbency of the PVA supperabsorbent composite resin were investigated.
