Polypropylene was reacted with maleic anhydride to improve the dyeability. The modified polypropylene was characterized by T-lR, SEM, and elemental analysis. This maleic anhydride reacted polypropylene showed a good dyeability with basic dye and disperse dye. The crystallinity of modified polypropylene was decreased with increasing the maleic anhydride content reacted onto polypropylene. The inherent viscosity of modified polypropylene was decreased because the chain scission occurred during the reaction. Blends of Polypropylene and modified Polypropylene with energy quencher were dyed excellently with disperse dyes, while those without energy quencher were dyed excellently with basic dyes. Blends of Polypropylene and modified Polypropylene mixed with energy Quencher show a lower crystallinity than those mixed without energy quencher.
