ABSTRACT
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.
