Abstract: Based on the difference of melt flow viscosity and solubility parameters betweenpolypropylene(PP)and poly(ethylene terephthalate)(PET),self reinforced blends of PP/PET in different ratio are made by extrusion,The fiber morphology of PET is observed un-der SEM and the diameter of the fiber fotind is from 2 to 10μm.Although the tensilestrength of the blend decreases slightly,the impact strength increases as compared to that of PP.

Key words: polypropylene, poly(ethylene terephthalate), polymer blend, in situ reinforced material
