Abstract: The lumped time distribution functions were proposed, which can be used for describing the
dynamicsystems with two or more than two states of the end of growing polymer chain during
chain addition polymerization.Numerical analysis of the lumped time distribution functions
was carried out. The method for calculating molecularweight distribution of polymer in the
stable free radical polymerization and more general cases was developed basedon the lumped
time distribution functions.

Key words: lumped time distribution function, molecular weight distribution, dynamic system
