| Abstract: | In the micellar polymerization to prepare associative polyelectrolyte, the influence of solution environment on hydrophobical micro-block length has been investigated. The results revealed that the aggregation number (Nagg) of surfactant micelles and micro-block length (NH) of polymers closely related to electrolyte concentration in polymerization solution, and all of the surfactant and charged monomer concentration can change the free counterion concentration (Caq) to affect Nagg and NH. Therefore, the NH with traditional calculation method which Nagg is looked as constant value was not accurate enough. Subsequently, we studied the attribution of NH to rheological properties. The results indicated that the micro-block length can increase obviously the reversible network strength in solution to make a few contribution of thickening properties of associative polymer. |
