Paper Abstract

The analytical expressions have been derived to calculate molecular weight distributions (MWDs) for a polymerization scheme that contains reactions of chain initiation, propagation and termination by recombination or disproportionation under polymerization initiation by arbitrary sequence of radiation pulses. These expressions can be applied to study MWD on initiation of polymerization both by arbitrary-duration pulses and by cw beam. MWDs calculated for methylmethacrylate polymerization by pulses sequence with different energy density are presented. Simple relations are derived for determination of chain termination constant kt from chains number distributions.
