摘　　要：合成了6种不同修饰度的聚丙烯酰胺疏水聚合物（ PAM1~PAM6），考察了聚合度、共聚物片段含量及疏水基团大小等内部因素和聚合物的抗剪切能力、剪切恢复性及抗盐性等外部因素对这些疏水聚合物分子间、分子内缔合的影响规律。Hydrophobically associating polymers are distinctive water-soluble polymers with a few hydrophobic groups in the hydrophilic macromolecular chain. Because of its unique amphiphilic molecule structure, it has special rheological properties. Six hydrophobically associating polyacrylamide derivatives with different modifi-cation monomers were synthesized. Their intramolecular and intermolecular association behavior by internal factors such as the degree of polymerization, the block copolymer content as well as the size of hydrophobic groups and the external factors of the resistance to shear, salt tolerance were investigated. The hydrophobic chain can improved the viscosity and salt resistance of polymers.
