Conformational and dynamooptical properties of a homologous series of poly(cetyltrimethylammonium 2-acrylamido-2-methylpropane sulfonates) with molecular masses ranging from 80 to 700 kkDa were studied in chloroform solutions by viscometry, dynamic light scattering, sedimentation and flow birefringence. The Mark-Kuhn-Houwink equations for this polymer in chloroform were obtained; the values of hydrodynamic diameter and the Kuhn segment length were defined as well as the value of intrinsic anisotropy of polarizability of the monomer unit.
