Processability and Mechanical Properties of Polymer Blends

Abstract

Polymer blend is one of the materials which has shown a highest growth rate in the polymer industries. One of the key factors to obtain the polymer blends with superior performance is to control the phase morphology and higher order structure of the blends. Sea-island morphology in the incompatible blends has to be controlled in the flow fields during shaping process. Even in the compatible blends, control of the crystalline higher order structure has to be carried out in the processing, if at least one of the component is crystalline. This report presents some of the researches related to the processability and the mechanical properties of polymer blends, including the researches on “PLLA/PDLA blend fibers”, “Polymer blends which involve a liquid crystalline polymer as a component”, and “Observation of deformation and recovery of minor phase in an incompatible polymer blend”.
