Preparation of R-PET/PP Alloy and Mechanical Properties

Abstract:

Polypropylene grafted with maleic anhydride (PP-g-MA) was prepared and then was used as compatibilizer in the alloy of r-PET/PP to improve the compatibility of different phases. The influences of grafting ratio of MA, the additive amount of PP-g-MA, and the ratio of r-PET and PP to the flowability and the mechanical properties of r-PET/PP were researched. The results obtained show that PP-g-MA can improve the compatibility of different phases; the favorite grafting ratio of MA on PP mainchains is 1.4%; when the additive amount of PP-g-MA is 12%, melt index of r-PET/PP indicates that not only the flowability of r-PET/PP becomes better but also the tensile strengthen is higher; the ratio of r-PET and PP should be designed at 20/80 in order to obtain satisfied results.
