Abstract: We have theoretically investigated the statistical mechanics and dynamics of the hyperbranched polymerization of ABg type, a relationship between the conversions of the two species and the Gibbs free energy is obtained, which makes the characterization of the polymer physical quantities can be simplified. Furthermore, the relationship between the dynamics and statistical mechanics of the system under study is pointed out, and then the conversions of the two species as a function of time is derived. Based on the results obtained in this paper, the hyperbranched polymerization can be investigated in a deeper level.

Key words: Hyperbranched polymer, Reaction dynamics, Statistical mechanics
