✦ Synopsis

Graft polymerization of styrene onto cellulose was investigated using ceric ions redox systems as initiator. The effects of reactant concentrations and of processing variables on the molar mass of grafted styrene on the cellulose were studied. A statistical model with the D-optimal design was used to describe the system. The optimum polystyrene molar mass obtained by simulation was compared to experimental data. The optimal reaction conditions for such a reaction were determined.

La polymerisation par greffage du styrene sur la cellulose a ete effectuee en presence d'ions cerique (IV). On a etudie I'effet de la concentration des reactifs (amorceur, cellulose, monomere) ainsi que les variables d'operation (agitation, temperature, temps de reaction). Un modele statistique a ete utilise pour obtenir les conditions optimales du procede. Les valeurs optimales pour la masse molaire ont ete determinees experimentalement et par simulations. Les conditions experimentales optimales ont ete determinees.
