Preparation of high water absorbent poly ( sodium acrylate) was carried out by inverse suspension polymerization in cyclohexane with Span-60 as suspension stabilizer, potassium persulfate as initiator and N, N ′ methylene bisacrylamide as crosslinking agent. 以环己烷为连续相,Span-60为悬浮稳定剂,过硫酸钾为引发剂,N,N′亚甲基双丙烯酰胺为交联剂,对反相悬浮聚合制备聚丙烯酸钠高吸水性树脂进行了研究。
Span-60 can be used to modified the surface of nano-diamond, and the surface of nano-diamond modified becomes lipophilic. 结果表明:用Span-60可以对纳米金刚石表面进行湿法改性,而且改性后纳米金刚石表面由亲水性变成亲油性。
