PP/PETStudy on the Thermal Properties of Polypropylene/Polyester blends Adding Nano Silica Dioxide:: PP/PETPP/PET(PP-g-MA)FTIRPP-g-MAPETTGAPP/PET/SiO22wt%DMAPP/PET/SiO2DSCPP/PET/SiO2ABSTRACT

In this experiment to investigate the different proportion of Silicon Dioxide on the PP / PET blends of thermal properties of the study. And polypropylene and polyester mainly to melt mixture of PP / PET blends , because of polypropylene and polyester are non-polar and compatibility was poor, so PP-g-MA was used as the compatibilizer, it is not easy mixing, it is necessary to use PP-g-MA to improve its compatibility. In consideration of FTIR, PP-g-MA would react with PET theoretically, but there is only a small portion, it looked like a physical blending. From TGA, it reached the highest temperature as 2wt% of SiO2 was added into PP/PET/SiO2. From DMA, the compatibility of blends was good. Form DSC, adding of SiO2 into PP/PET/SiO2, the crystallization temperature was increased.1. polyblend1.1 1954Giulio Natta10.90~.091g/cm324h0.01%8~150.01%8~152HDPE PPPP71073164~170100150-35-35-35-353PP164~1701001502HDPE1.2 PETJRJT1941JRJT194119481948 PETPET50501966PET,1966PET, 19761976PETPPPETPPPPPET1.31,2PETPPPP/PETPP-g-MAPPPPMAPET 1998K.
