Effect of POE Chain Structure on Structure and Properties of PP/POE Blends
In order to investigate the effect of the polyolefin elastomer(POE)chain structure difference on the structure and properties of polypropylene/polyolefin elastomer(PP/POE)composites,POE with different chain structure,talc masterbatch(Talc)and PP were melt blended to prepare PP/POE composites.The structure and properties of PP composites were characterized by a melt flow rate tester,an electronic universal tester,a cantilever impact tester,a thermogravimetric analyzer(TG),a differential scanning calorimeter(DSC)and a field emission scanning electron microscope(FESEM).The results show that compared with an ethylene-1-butene copolymer(POE-C4),an ethylene-1-octene copolymer(POE-C8)not only maintains the tensile strength of PP/POE composites,but also improves the toughness of the composites.The difference in POE chain structure has no obvious effect on the thermal stability of PP/POE composites.
