Abstract:

Blending of polymers offers attractive opportunities for achieving unique property combinations and for improving mechanical toughness but requires knowing how to control interactions to achieve miscibility or phase separated blends with proper interfacial coupling. Without controlled interactions, blends do not perform as desired and some strategy for compatibilization is necessary. Preformed block or graft copolymers may be added to act as interfacial agents or these may be formed in situ by reaction of suitably chosen functionalized polymeric components for control of phase morphology and the interface between these phases to obtain useful mechanical properties. This paper reviews some of the strategies currently being used to couple the phases in multicomponent engineering polymer alloys. MM
