Abstract The effects of anionic surfactant SDS on the solution viscosity of various kinds of polymers were investigated. The results showed that: for the nonhydrophobically associating type polymers --- ultrahigh molecular weight polyacrylamide MO-4000, KYPAM-2 salt resistant polymer, the surfactant SDS has no effect on their solution viscosity basically; whereas for those hydrophobically associating type polymers ---allyl ammonium hydrophobically associating type polymer and admixed polymer, the surfactant has great influence on the solution viscosity of the polymers, there exists a maximun value.

摘要 在不同条件下，进行了不同含量阴离子表面活性剂SDS对不同类型聚合物溶液粘度的影响研究，结果表明SDS对非疏水缔合类聚合物棗超高分子量聚丙烯酰胺MO-4000、KYPAM-2抗盐聚合物溶液的粘度基本上没有影响，而对疏水缔合类聚合物棗烯丙基铵型疏水缔合聚合物及共混聚合物(疏水缔合聚合物与SDS的混合物)溶液的粘度影响很大，存在极大值。
