摘　　要：高吸水性树脂是近年来迅速发展起来的一类新型功能高分子材料,其应用十分广泛,但该类材料尚需急待解决三大问题,即降低成本,提高吸水后凝胶强度,提高凝胶耐盐性,后者已有文献报道,而前两个问题还没有得以解决.作者于1978年曾用丙烯酰胺(AM)和甲叉基双丙烯酰胺碱水溶液共聚交联,水解、造粒、烘干、粉碎。In this paper, the relationship between the copolymerization crosslinking condition for the acrylamide and N,N' -methylene-bis-acrylamide containing a large amount of bentonite in alkaline solution and the water absorption of the partially hydrolysed crosslinked polyacryla-mide was studied. The intensity and the structure of gel were measured.It was found that the intensity of the partially hydrolysed crosslinked polyacrylamide containing bentonite after absorbing water is many times larger than that of one without bentonite.
