The second radius of gyration of hyperbranched polymers formed in self-condensing vinyl polymerization system in the presence of core initiators was studied by the method of Monte Carlo simulation, in which the unequal reactivity was taken into account. As a result, the roles of the reactivity differences in two types of active groups, the molar ratio and functionality of core initiators were mainly discussed, and it was found that these factors could give rise to a significant influence on the radius of gyration of hyperbranched polymers with and without a core initiator. This provides some useful clues for regulating the dimension of the hyperbranched polymers in the relevant experiments.
