Research Abstract

The deformation and recovery of a poly (isobutylene) droplet embedded in a poly (dimethylsiloxane) matrix are directly observed from two directions after application of a large step shear strain. The droplet shape and recovery time strongly depended on the magnitude of the applied strain. Just after application of a large strain, a droplet deforms almost affinely to a flat ellipsoid. It then changes into a rod-like shape, a dumbbell and to an ellipsoid of revolution, and finally to a sphere. Model calculations show that the primary driving force for the shape recovery is the interfacial energy in order to reduce the surface area of the deformed droplet.
Dynamic viscoelatic properties of polycarbonate as a engineering plastic/polystirene blend melts were investigated. The average radius of droplets of dispersed phase was estimated from transmission electron micrographs of the blend. Further the interfacial tension between these two polymers were determined by comparison of the dynamic data with thge Plierne theory, and found to agree fairly well with the values obtained by other methods.
Tribological properties of polyamide 6/polyolefin blends were investigated. It was found that the tribological properties of the blends are strongly affected by the phase morphology, crystalline structure, and interfacial adhesion between parent polymers as well as the composition of the components.
