Solution properties of a hyamine based on N,N‐dimethyl diallyl ammonium chloride–acrylamide copolymer

Abstract

A hyamine based on N,N-dimethyl diallyl ammonium chloride-acrylamide copolymer was successfully synthesized in this study. Solution properties of this hyamine including electrical conductivity and viscosity behavior were studied in detail, and effects of temperature and counter ion concentration on electrical conductivity of the solution were also discussed. It was found that a solution of hyamine in water showed a typical viscosity behavior of polyelectrolytes, which followed the Fuoss equation. With the increase of ion radius (cationic ion or anionic ion), or with the increase of salt concentration, the shrinkage degree of the polymer chain increased, with a concomitant decrease in reduced viscosity and intrinsic viscosity and an increase of Huggins constant. © 203 Wiley Periodicals, Inc.

“…Practical importance of DADMAC homopolymer and copolymer studies involving polymerization mechanism and kinetics, molecular characterization, and solution properties of this system have drawn great interest. Highly hygroscopic nature of PDADMAC causes difficulties in characterization polymerization reaction by chemical methods or isolation and gravimetrically . The electrostatic repulsion between the ion and the charged macroradical depend on the pH value of the medium and the concentrations of ionic species.…”
