【摘要】 腈纶废丝首先在碱性条件下水解，再经中和、洗涤后，加入交联剂甘油环氧树脂加热交联即得高吸水性树脂。实验表明，甘油环氧树脂的最佳用量在０．３０％左右，所得吸水树脂吸水率稳定在６００～８００ｇ／ｇ之间。更多还原

【Abstract】 the waste polyacrylonitril was hydrolyzed with aqueous of NaOH to form polyacrylamade containing carboxyl and amide functionalities.Then the super water-absorbent resin was prepared by crosslink of the hydrolysate and glycerin diglycidyl ether.The water absorbency of the resin is 600-800g/g,the optimal concentration of glycerin diglycidyl ether is about 0 30%。更多还原
