Parallel reactors are well known in the field of for instance polymers. These reactors are commonly used to manufacture by an in-line polymerization process composites characterized by high viscosity, or polymers as for instance polystyrene, poly(glycolide), poly(dioxane), poly(epsilon-caprolactone) and, most commonly poly(lactides), polycaprolactones and poly(glycolide), characterized by a high melt 50e0806aeb frexere
