Abstract

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.
