New approach to synthesis of core-shell latices is proposed in the presented work. The method is based on the peroxide macroinitiators utilization for formation of the seed particles with tethered to their surface peroxide moieties. As a result, initiation and chain-growing reactions of polymerization of the shell-forming monomer are localized precisely at the seed latex interface. That allows to diminish consumption of this monomer required for complete encapsulation of a core polymer. The advantages of this new method over the conventional core-shell technology are reflected in improving the properties of polymer coating derived from such latices.
