A kinetic model of the amphiphilic star block copolymerization is developed. The star polymer species, resulting from star polymerization with dendrimer cores and hydrophobic monomers, are used as macroinitiators and initiate the graft polymerization of the hydrophilic monomers. Analytical expressions for the size distributions for the species formed in every step are derived. The method with monomers added to the reaction system in batches decreases the polydispersity index for the products obtained. It reaches a minimum if the monomer feed quantity is equal in every step. Therefore, the dimension and structure of the amphiphilic star block copolymers produced can be designed by using the proposed kinetic mechanism.
