Abstract
The efficiencies of two azo initiators in the polymerization of allylamine salts in water and organic solvents were compared. The hydrodynamic and molecular characteristics of poly(allylamine hydrochloride) in 0.1 M NaCl in the molecular mass range M×10−3=18−65 were studied, and the scaling relationships were derived for the intrinsic viscosity ([η]=7.65×10−3M0.8±0.1), translational diffusion coefficient (D0=2.41×10−4M−(0.59±0.05)), and velocity sedimentation coefficient (s0=2.77×10−15M0.41±0.05). The hydrodynamic data were interpreted in terms of electrostatic long-range and short-range interactions. The equilibrium rigidity of poly(allylamine hydrochloride) chains in 0.1 M NaCl and its structural and electrostatic constituents were quantitatively estimated. It was shown that the conformation of poly(allylamine hydrochloride) chains in pure water is close to rodlike.
