The Influence of the compatibilizer Characteristics on the interfacial characteristics and phase morphology of aPA/SAN blends

The main objective of this work is study the influence of the methyl mathacrylate maleic anhydride copolymer (MMA-MA) compatibilizer properties such as molecular weight and maleic anhydride content in the characteristics of amorphous polyamide and styrene acrylonitrile copolymer (aPA/SAN) blends, correlating their interfacial characteristics and phase morphology.

Even though the system aPA/SAN is thermodynamically immiscible, it shows morphology of phases with small particles of SAN. The addition of MMA-MA copolymer with high degrees of MA led to an increase of the SAN phase particle size. With SAXS technique, it was possible to determine the interface thickness and the results shows that the characteristics of the interface do not change with the variation of the compatibilizer characteristics.

Abstract

The main objective of this work is study the influence of the methyl mathacrylate maleic anhydride copolymer (MMA-MA) compatibilizer properties such as molecular weight and maleic anhydride content in the characteristics of amorphous polyamide and styrene acrylonitrile copolymer (aPA/SAN) blends, correlating their interfacial characteristics and phase morphology. The blends aPA/SAN, with and without the compatibilizer, prepared were characterized by transmission electron microscopy (TEM) and small angle X-rays scattering (SAXS). The results show that the maleic anhydride concentration has a more significant effect on the blend properties than the molecular weight of the MMA-MA copolymer. Even though the system aPA/SAN is thermodynamically immiscible, it shows morphology of phases with small particles of SAN. The addition of MMA-MA copolymer with high degrees of MA led to an increase of the SAN phase particle size. With SAXS technique, it was possible to determine the interface thickness and the results shows that the characteristics of the interface do not change with the variation of the compatibilizer characteristics. The results observed in this work indicate that the viscosity ratio is very important factor on the formation of the phase morphology.
