Abstract: Molecular weight distribution functions are obtained by graph analysis method. With different methods, such as conversion, the implicit function and Monte Carlo method, the difficulties in calculation are solved, molecular weight distribution curves are obtained. The influence of different termination and propagation rates on molecular weight distribution is discussed. Diffusion controlling in styrene bulk polymerization is concerned, polystyrene molecular weight distributions are obtained and the results are in agreement with the experimential observation.

Key words: Polymerization kinetics, Graph analysis, Monte Carlo method, Implicit function, Molecular weight distribution
