Abstract

Statistical and kinetic methods to model step polymerization of AB₂ type of monomers (A and B stand for functional groups) are briefly reviewed and the relationships linking conversion or reaction time with averages of polymerization degree are derived for systems fulfilling the Flory-Stockmayer assumptions, i.e., for those with no reactivity changes of functional groups and absence of intramolecular linking. Results of kinetic studies are also presented for polymerization of 3,5-diaminobenzoic acid, aided with N,N'-diisopropylcarbodiimide, carried out at room temperature in NMR test tubes. For reaction carried out in dimethylsulphoxide, the relationship between conversion and time is well described by the simplest kinetic model. It was stated that in the case of reaction carried out in dimethylformamide the reactivity of the second amino group in the monomeric units seems to be ten times lower than that of the first one.
