摘　　要：针对实验室自制有机铝交联体系L-2和酚醛交联体系FA-1,从性能和结构方面进行对比性研究。结果表明,L-2的成胶时间比FA-1长,FA-1的耐温抗盐能力均比L-2强。通过电镜扫描照片分析得出,交联剂与聚合物分子之间形成了网络结构、树枝状结构、层状结构,并且结点增多结构增强,增强了体系的耐温抗盐能力。FA-1比L-2的交联点更多,结构更为复杂,其稳定性进一步增加。This paper has researched weak gel system L-2 and FA-1 on gel time, temperature system which forms by self-made crossIinking resistance, salt tolerance and the configuration and structure by electronic microscope. We can draw those conclusion： gel time of L-2（72 h） is more than that of FA-1 （12 h）; the temperature resistance and salt tolerance performance of FA- 1 （90℃, 20×10^4 mg/L） is more stronger than those of L-2（75 ℃, 16×10^4 mg/L）. Through the electronic microscope photos, crosslinking agent and polymer molecular form the structure of reticulation, arborization, sandwich, which enhance the performance of weak gel system. The linked points of FA-1 is more than that of L-2 and the structure is more complicated.
