Abstract
Polymer blends of commercial polyphenylene oxide (mPPO) and polypropylene (PP) are immiscible and incompatible in blend system. Maleic anhydride-grafted-copolymer has been employed as in situ compatibilizer for the mPPO and PP blends. This copolymer contains reactive anhydride functional groups that were able to react with mPPO at [sbnd]CH3 side methyl groups [sbnd]OH terminal groups under the melt conditions. The PP-g-MA copolymer reduces the interfacial tension between the two polymers and act as a bridge between them to make compatible. The blends have been characterized using FTIR, SEM, and its mechanical behavior.
