Mark‐Houwink coefficients and radius of gyration dimensions are presented for six unfractionated cationic polyelectrolytes of the poly(dimethylamine‐epichlorohydrin‐ethylendiamine) type. The copolymer system was studied in .05M, .10M, and 1.0M NaCl, and .12M NaClO 4 aqueous solutions. Their solution behavior, as studied by intrinsic viscosity and light‐scattering technique, suggests these polymers adopt a somewhat spherical or star‐like conformation in aqueous salt solutions.
