Abstract The polｙpropｙlene／polｙethｙlene(PP／PE) blends with different weiｇht ratio were studied bｙ FTIＲ spectroscopｙ． The characteristic absorption bands of PP and PE in different blends were compared． It was foｕnd that the ratio of the characteristic absorption peaｋ areas of PP to those of PE is correlated with the weight ratio of PP to PE in the blends. Based on the above resｕlts，FTIＲ mappinｇ techniｑｕe was applied to characteriｚe the samples prepared bｙ embeddinｇ PP fiber into molten PE film，and the distribｕtion of PP and PE in the blends can be obtained from the ratio of the characteristic peaｋ areas of PP to PE． Good aｇreements have been observed between the IＲ mappinｇ imaｇe and the imaｇe obtained ｕsinｇ polariｚed optical microscope． These resｕlts indicated that FTIＲ mappinｇ techniｑｕe is an effective tool to investiｇate the phase separation behavior of polｙmer blends based on the ratio of the characteristic peaｋ areas of different polｙmers．
