摘　　要：以丙烯酸胺(AM)和十六烷基二甲基烯丙基氯化铵(C16 DMMAC)为原料,无皂共聚合成了疏水缔合聚合物PAMC16-X。考察了疏水单体含量、聚合物初始浓度、NaCl浓度及温度对PAMC16-X稀溶液性质的影响。并采用团簇理论对其稀溶液性质和Huggins系数的变化进行了解释。结果发现,该理论可以合理解释有关疏水缔合聚合物稀溶液的一些实验现象,但也存在一定问题。A hydrophobically associating polymer（PAMC16 - X） was prepared by nonsoap copolymerization of acrylamide（AM） and hexadecyl dimethyl allyl ammonium chloride （C16 DMMAC）. The effects of the hydrophobic monomer content, initial polymer concentration, NaCl concentration and temperature on the properties of the dilute PAMC16 - X solution were studied, The dilute PAMC16 - X solution properties and Huggins coefficient changes were explained trying to use cluster theory.The results showed that the cluster theory might be used to explain some experiment results of hydrophobically associating polymer dilute solution, but there were sill some shortages.
