| Abstract: | The structure and composition of two high impact polypropylene(HIPP) used for washing machine were characterized by nuclear paramagnetic resonance(13C NMR),gel permeation chromatogtaphy(GPC),polarized light microscope and scanning electron microscope,and the results were correlated with product performance to study the factors affecting the performance of impact polypropylene.The results show that the content,composition,phase structure,molecular weight and molecular weight distribution of the rubber phase in the impact polypropylene,the crystallinity and crystallization temperature of the impact polypropylene have an important effect on the properties of impact PP. |
