【Abstract】 In this paper,the morphology property relationship in polypropylene/polyamide1010 (PP/PA1010=90/10,volumetric ratio) is studied.By applying the on line light scattering technique,the correlation distance and particle distribution are discussed in this system.It is found that the significant changes in morphology occurred during the first 1 min of mixing.After that time,the morphology of PP/PA1010 blend went into a steady state.This trend was also reflected in the mechanical properties.In addition,the effective integral model gave a closer prediction to the experiments on the blends with a steady state morphology.更多还原
