Abstract:The miscibility of isotactic polypropylene-atactic polystyrene blends using dilatometric, TOA, DAT and stress-strain methods were studied. It appears that the blends are heterogeneous, having two glass transition temperatures. However, some interactions between components are evident to change theTgs of their amorphous phases and theTm of isotactic polypropylene crystals. The results are discussed on the basis of the blends' thermal and tensile properties.
Keywords:Polymer blends  miscibility of iPP with aPS  glass transition  thermal and tensile properties
