合成条件对高吸水树脂吸液能力的影响
The Effect of Polymerization Conditions on Absorbency of Acrylic-Based Polymer
【摘要】 在不同温度、不同加料方式下用溶液聚合法合成了丙烯酸系高吸水树脂 (PAAS) ,测定了这一系列树脂在蒸馏水、自来水、0 .9%的生理盐水、K2 SO4 和MgSO4 溶液中的吸液能力 ,对树脂进行了红外分析
【Abstract】 The absorbency of acrylic-based polymer in distilled water, 0.9%NaCl solution, tap-water and K 2SO 4, MgSO 4 solutions was studied.The polymers was polymerized under reaction conditions of various temperature and different style of feeding monomer. The infrared spectrum of acrylic acid, N Nmethylene bisacrylamide and the polymer were also analyzed here.
