采用可逆加成-断裂链转移共聚法制备了不同聚合度和组成的2-(丙烯酰胺基)-2-甲基丙磺酸钠和甲基丙烯酸正己酯两亲统计共聚物样品，并用光散射、荧光、粘度和尺寸排斥层析等方法研究了它们在0.1M氯化钠溶液中的自聚集结构。共聚物样品的主要成分是由2-7个聚合链组成的聚集体，具有1-5个疏水微区，这取决于聚合度和组成。
Amphiphilic statistical copolymer samples of sodium 2-(acrylamido)-2-methylpropanesulfonate and n-hexyl methacrylate with different degrees of polymerization and compositions were prepared by reversible addition - fragmentation chain transfer copolymerization, and their self-aggregating structure in 0.1 M aqueous NaCl was studied by light scattering, fluorescence, viscometry, and size exclusion chromatography. Major components of the copolymer samples were aggregates consisting of 2-7 polymer chains and possessing 1-5 hydrophobic microdomains, depending on the degree of polymerization and composition.
