Abstract

RIVERO, Pastor. Simulation of Free Radical Polymerization in the Entire Conversion Range. Inf. tecnol. [online]. 2006, vol.17, n.3, pp.79-85. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642006000300012.

In this study the simulation of methyl methacrylate free radical polymerization is presented, in order to obtain the conversion and the average molecular weights, considering diffusion-controlled initiation, propagation, chain transfer and termination reactions. The central part of the work is the application of a method previously proposed by the authors for the approximate solution of the kinetic equations when the termination rate coefficient depends on the chain length of the radicals The strategy of the method is to reconstruct the chain length distribution of radicals from its moments to obtain the termination rate distribution moments. The calculated conversion and average molecular weights are in good agreement with previously reported experimental data.

Keywords : polymerization; free radical; methyl methacrylate; termination rate; chain length.
