【摘要】 采用反相悬浮聚合法合成了3种聚丙烯酸系列吸水树脂:聚丙烯酸钠(PAA)、丙烯酸-丙烯酰胺共聚物(P(AA/AM))和丙烯酸-马来酸酐共聚物(P(AA/MA))。对3种树脂的吸水性、保水性、耐候性和耐电解质等性能进行测试比较。结果表明,P(AA/MA)的吸水性能最优异,10 min内吸蒸馏水量可达3578.4 g/g;在一定的温度或压力范围内,3种树脂均有良好的保水性能,在不同温度下储存均能保持各自的吸水性;P(AA/MA)的耐电解质性能较为突出,吸生理盐水量可达107.2 g/g,其综合性能最好。

【Abstract】 Three polyacrylate superabsorbent polymers:sodium-polyacrylate(PAA),poly(acrylic acid-coacrylamide)(P(AA/AM)) and poly(acrylate acid-co-maleic acid)(P(AA/MA)) were synthesized by inverse suspension polymerization(ISP).Systematic tests and comparison were taken at water absorption,water retention,weather resistance and electrolyte resistance of the product.The results show that P(AA /MA) possesses the best water absorption performance with an absorbency for distilled water of 3578.4 g/g in10 min.The three polymers all have good quality of water retention within a range of temperature and pressure,with P(AA/MA) showing the best in this performance.The three polymers all can keep their water absorption in different temperature storage,and P(AA/MA) has excellent quality toward electrolyte resistance,with an absorbency for normal saline of 107.2 g/g.Overall,the comparisons show that the comprehensive performance of P(AA/MA) is the best.
