| 摘 要： | 采用一种木质纤维素与丙烯酸（AA）／丙烯酰胺（AM）接枝共聚，以N，N＇-亚甲基双丙烯酰胺（NMBA）为交联剂，以过硫酸铵（APS）为引发剂，制备出耐温、耐盐、缓膨性能好、高强度的树脂凝胶。考察了交联剂用量、引发剂用量，木质纤维素用量及单体配比对共聚物性能的影响，合适的接枝共聚反应条件为：木质纤维素用量3．0％，AA与AM质量比0．75：1．25（单体质量占体系总质量的30％），引发剂和交联剂用量分别为0．25％和0．15％。

| Abstract: | A resin gel with heat resistance,salt tolerance,and high strength was prepared by graft copolymerization of lignocellulose with acrylic acid(AA)/acrylamide(AM),using N,N' - methylene bisacrylamide (NMBA) as crosslinker and ammonium persulfate(APS) as initiator.Factors such as dosage of crosslinker, initiator,lignocellulose and mass ratio of monomers influencing the properties of copolymers were examined, the optimum conditions for graft copolymerization were as follows:lignocellulose content 3.0%,mass ratio... |
