Abstract

Batch-foaming of miscible, immiscible and compatibilized polymer blendsystems over a wide compositional range was carried out using carbon dioxideas a physical blowing agent. The resulting foam morphology was characterizedby a detailed evaluation of foam density as well as of the cellularparameters. With regard to multiphase blends, transmission electronmicroscopic observations further provided a detailed insight into the cellwall morphology. The role of the melt-elongational properties and of theglass transition behavior of the various blend systems on the foamingcharacteristics was systematically elucidated. While the miscible blendsshowed a simple additivity behavior with regard to their foamingcharacteristics and properties, a significant influence of the initial blendmorphology is demonstrated for the multiphase blends.
