Abstract
A procedure is developed that allows the calculation of chain length d istributions of polymers prepared by periodic modulation of the initia tion process, considering termination by disproportionation and chain transfer. For the case of a (pseudostationary) laser-pulse initiated p olymerization process a closed solution can be derived for the chain l ength distribution (cld) of dead polymer and its 0(th), 1(st) and 2(nd ) moments. By analysis of the detectability of the ''extra-peaks'' app earing in the cld (which represent the key for the determination of pr opagation constants) as a function of the parameters chosen the optimu m conditions can be predicted for experiments.
