木质素基丙烯酸系吸水性树脂研究进展

吸水性树脂是一种功能高分子材料,它具有很强的吸水性能。它由低分子物质经聚合合成的高聚物或者由高聚物经化学反应所制成。20世纪70年代后期以来,它的开发取得了巨大进展,在工业、农林业、医疗卫生、日常生活等领域得到广泛应用。本文总结高吸水性树脂的发展历史,应用领域、分类,分析目前高吸水性树脂的研究与开发中存在的问题,阐明木质素基吸水性树脂的研究意义。

Progress in the research of ligninsulfonate-acrylic acid superabsorbent polymers

Superabsorbent polymer is a type of fuctional polymer material with strong absorbent characters. It is polymer synthesised from materials with low or high molecular weight. Enormous advances have been made in the researches on the superabsorbent polymer since the 1970s and wide usage of the superabsorbent polymer is found in industry, agriculture, medical treatment, sanitation, daily accessories. In this paper, development, utilization, classification and the synthesis, and the absorbing property of superabsorbent polymers have been summarized. Problems in current reserch have been proposed and significance of the reseraches on sodium ligninsulfonate-acrylic acid superabsorbent polymers are elucidated.
