Polymer Blends Forming

Abstract

The key to optimizing polymer blends performance is control of morphology. Distinct types of morphology are required to improve specific properties. The matrix/dispersed phase type is necessary to obtain the maximum impact strength, while dual phase co-continuity will yield better stiffness/ductility balance and dispersion of lamellar domains allows to modify the barrier performance. Optimized properties therefore result from strict control over processing conditions and equipment, and from methods of generating and stabilizing the morphology, such as reactive compatibilization.
