Assuming the ideal polymerization kinetics and a constant polymer/monomer ratio, the branched architecture formed with the coexistence of chain transfer reaction to polymer is investigated by using a Monte Carlo simulation method, both for the conventional and living free-radical polymerization (FRP). The universal relationships, unchanged by the polymer transfer constant and the primary chain length distribution, are found for the mean-square radius of gyration Rg(2), and the maximum span length L-MS. The g-ratio of Rg(2) of the branched molecule to that for a linear molecule, as well as the weight fraction of L-MS chain in a polymer, as a function of the number n(b) of branch points per molecule does not change with the kinetic parameters, beyond the differences of conventional and living FRP. A single linear equation nicely covers the relationship between Rg(2) and L-MS for both the conventional and living FRP. The characteristics found in this article contain many new insights into the complex branched polymer formation that stimulate further research. 收起
