Ultrasonic studies of aqueous solutions of poly diallyl dimethyl ammonium chloride

Poly diallyl dimethyl ammonium chloride (DADMAC) was synthesized by solution polymerization technique using potassium peroxomono sulphate. The ultrasonic velocity and density for solutions of the synthesized poly(DADMAC) in the different concentration ranges are measured at three different temperatures 308, 313 and 318K. Parameters like apparent molal compressibility, apparent molal volume and molar solvated volume in terms of molar hydration number are computed on the basis of Padova model. The variation of apparent molal compressibility and molar solvation number indicates interaction between the polymer and the solvent.
