The phase formation and development of polypropylene/polystyrene (PP/PS) blends during mixing were investigated by pattern analysis of scanning electron microscopy.The effect of compatibilization of styrene-ethylene-propylene block copolymer (SEP) on polypropylene/polystyrene (PP/PS) was proved by small angle laser scattering (SALS)
which confirmed the validity of SALS to describe the morphology of blends.The morphology development was investigated by analysing the variation of phase dimension dg.Further
the fractal character of distribution of phase dimension was examined in terms of distribution function to study the dynamics of phase dispersion.
