In the free (unconstrained) sedimentation mode titanium dioxide suspension (anatase) kinetics at dosing of five random copolymers of acrylamide and dimethylaminoethyl methacrylate hydrochloride with high molecular mass (M>3,6·10 6) and with various concentrations of ionic groups β was investigated. Based on kinetics analysis and the results of dynamic light scattering method, the flocculation mechanism dependence from the cationic copolymer of acrylamide ionic units in hybrid polymer-inorganic systems is: β 20% - largely bridged, and when β> 20% - neutralization. Quantitatively the optimal mode of flocculation in a dispersed system with polymer-inorganic hybrids was determined at β = 10%
