Studies on the Effect of Polyamide-6 onto Modified Polyphenylene Oxide Matrix in Presence of Fumaric Acid as a Compatibilizer

Abstract

Polymer blends of modified polyphenylene oxide (mPPO) and polyamide-6 (PA-6) are immiscible and incompatible in nature. However fumaric acid (FA) is used as a compatibilizer for the compatibilizing of mPPO/PA-6 blend systems. During melt compounding functional groups of the polymer components were reacted in the presence of a compatibilizer in the extruder. The blends were characterized by using FTIR, SEM, and mechanical behavior testing. The concentration of FA compatibilizer varies inversely w.r.t. PA-6 concentration in the blend systems. However the blend composition of PA-6 (10%) shows good miscibility among the other blend systems under present study.
