Abstract
High density polyethylene (HDPE)/Nylon-6 blends of varying concentrations and compatibilized with Na-neutralized ethylene-methacrylic acid ionomer were prepared and characterized. Specimens in sheet form were prepared and tensile strength, elongation, Izod impact resistance, hardness, insulation resistance, arc resistance, dielectric strength, and so on were measured. Thermal testing such as thermogravimetric analysis and differential scanning calorimetry were carried out to study the effect of comapatibilization on the thermal properties of blends. This study reveals that by addition of ionomer, various properties of the blend improve significantly. The optimal quantity of ionomer is about 3%. After further addition of ionomer these properties deteriorate. Morphological study of fractured surface by scanning electron microscope indicates that the immiscible polymer becomes miscible by compatibilization with ionomer.
