The polycondensation of linear polymers, based on type AB monomers, was simulated using the dynamic Monte Carlo method with the bond-fluctuation lattice model. Besides chain configurations, the conventional parameters such as the extent of reaction, degree of polymerization, molecular weight distribution and their evolution with reaction time can be obtained via statistics. The scaling law of the coil size versus chain length during polymerization has also been confirmed. This method is proved to be practical to perform simulation of polymerization kinetics with the advantage that the spatial information such as configuration of self-avoiding chains during polymerization can be obtained. Finite size effect has been further examined and discussed.

Key words: polycondensation, dynamic Monte Carlo simulation, lattice chain, chain configuration, finite size effect
