KINETICS OF 2-PENTADECYLANILINE POLYMERIZATIONS IN MONOLAYERS - RELATIONSHIPS BETWEEN EXPERIMENTAL-DATA AND A NEW THEORETICAL-MODEL

In this paper we have presented a simple theoretical model that provides a detailed understanding of aniline polymerization kinetics in a monolayer. Even though the model is primitive, it agrees very well with our experimentally measured data. The rate constant and activation energy obtained in our previous study from the modified Gee and Rideal equation have been found as geometric and arithmetic means, respectively, of values which correspond to the initiation and propagation steps. This model allows us to predict an average degree of polymerization and thus an average molecular weight and the fraction of reacted monomer at any stage during the polymerization reaction. Also, some predictions regarding the temperature dependence of molecular weight can be made from this model.
