Resumo(s)
This paper summarizes recent developmentsof a rigorous kinetic method for medelling of a non-linear irreversible polymerizations with a finite number of intramolecular cyclizations. Some Changes have been introduced in order to perform much more efficient computations with polyadditions. The procedure for obtainning z-averaged distributions of gyration radius for gaussian chain molecules is briefly described. Chain lengh distributions gel properties (such as the concentrations of elastically active junctions and chains) and average gyration radii were computed for non-radical copolymerization of monomers with one and with two terminal double bonds. Predictions of average molecular weights gelation for free radical copolymerization of that some kind monomers and vinyl acetate homopolymerization are also discussed.
