Abstract
A lamellar model is used to evaluate the effects of striation thickness distribution on the behaviour of an unpremixed three component random block copolymerization. A lumped competitive-parallel kinetic scheme is used to describe the polymerization, and the diffusion-reaction process is solved over a periodic set of striations. The results indicate that using an average striation thickness to describe a reacting system may greatly overestimate the conversion, especially if the striation thickness distribution is wide. Large regions of unreacted monomers may remain isolated at long times, even for a system which is macroscopically stoichiometric.
