Abstract

The influence of stretching history on unpremixed polymerizations is evaluated by studying concurrent mixing, diffusion and reaction in shear and elongational flow fields. A lamellar model is used in conjunction with both a lumped competitive-parallel kinetic scheme and a polymerization kinetic scheme based on a moment method to model the diffusion-reaction process. Two case studies are presented and analysed in detail. Although the evolution of the polymerization is very different for the two stretching histories, many of the final properties (gross concentration profiles, average molecular weight, etc.) are similar. Other properties, such as the maximum molecular weight, are strongly path dependent.
