摘要

采用氯磺酸磺化法制备了聚乙烯醇硫酸钠（SPS），以工业级丙烯酸和SPS为原料采用静态溶液聚合法合成了具有良好吸水、吸盐水性能及较高热稳定性的聚丙烯酸（盐）-聚乙烯醇硫酸钠互穿网络型高吸水性树脂（SA-IP-SPS），红外光谱、热重分析、硫含量分析结果表明了SA-IP-SPS互穿网络结构的形成.对SPS含量、PVA分子量的考察结果表明：PVA相对分子质量在90000～124000，SPS含量在3%左右时得到的SA-IP-SPS高吸水性树脂吸附性能最高（吸水900g·g-1，吸0.9%食盐水97 g·g-1）.

Abstract

Sodium PVA sulfate(SPS) was prepared through the sulfonation of the hydroxyl groups of PVA by using chlorosulfonic acid as sulfonating agent. Industrial grade acrylic acid and SPS were used as raw materials of static solution polymerization to synthesize acrylic acid-based superabsorbents inter-penetrated with sodium PVA sulfate (SA-IP-SPS) which have higher water and saline absorbency.Characterization results with IR

TG and sulfur content measurement proved the formation of inter-penetrating network structure in SA-IP-SPS superabsorbents. The effects of SPS content and PVA relative molecular mass on the absorbency of the superabsorbents were studied and the optimized SPS content and the PVA relative molecular mass were 3% and 90000—124000 respectively. Under the optimized reaction conditions

the water absorbency was about 900g·g-1

and the 0.9% NaCl solution absorbency is 97 g·g-1.
