The kinetic model of the amphiphilic copolymers with hyperbranched core and linear arms was developed for both semibatch and one‐pot polymerization. The molecular size distribution functions of the species obtained and the various molecular parameters were analytically derived. The topological structures and molecular parameters of the products depend on initial mole feed ratios of the reactants. Under the same reaction conditions, the polydispersity index of the products resulted from semibatch is smaller than that of the one‐pot process and there are more terminal units on the surface of hyperbranched macroinitiators from semibatch process. Accordingly, the topological structures of the amphiphilic hyperbranched copolymers and the successive self‐assembly shapes can be designed by the suitable initial conditions of the polymerization.
