The synthesis of block-copolymers of controlled chain length and content of end peroxide groups via polymerization of dimethylaminoethyl methacrylate initiated by Ce 4+-PEG system using a functional peroxidecontaining chain transfer agent was developed. Rheological and colloidal-chemical characteristics of novel polyampholitic surfactants were studied.

Abstract.1 Metal-complex macroinitiators were successfully applied for the synthesis of polymer nanocomposites with core-shell structure by two-stage water dispersed polymerization. On the first stage, formation of monodispersed polymer particles of desired size and functionality is achieved by target variation of macroinitiator concentration, content of metal cations in its structure, and pH of medium. Initiation of grafted polymerization from the surface of seeded particles is provided by residual peroxide moieties of macroinitiator.
