Study on Reactive Blend Systems of PA1010/ABS/PP

Abstract

The impacts of multi-monomers melt grafting blends of maleic anhydride(MAH) and Styrene (St) on the crystallization behavior, morphology and mechanical properties of PA1010/ABS/PP blends were studied through the methods of SEM,themal analysis, mechanical properties analysis. The results showed that the graft copolymer generated in situ by the anhydride groups of g-PP and the amino end of PA1010 reduced the interfacial tension of blends efficiently, and the interaction of the styrene groups of the graft copolymer and ABS is helpful to improve the compatibility of three components during the melt blending process. The size of dispersed phase in blends is reduced obviously and the mechanical properties have a great improvement when the percentage of g-PP in the PA1010/ABS/PP blends increases to 10%. The tensile strength of the compatibilized PA1010/ABS/PP blends is improved by 11.7%,and the impact strength and elongation at break are increased 4 times and 4.9 times, respectively.
