The grafting process of N-carbamyl maleamic acid (NCMA) onto polypropylene was performed in the molten state using a twin extruder. The modification process was carried out in transient state using organic peroxide as initiator. Residence time distributions were determined by means of in-line optical detector placed at the exit of the extruder.  The polymers were characterized using Fourier transform infrared spectroscopy to verify the grafting of NCMA.
