It was generally observed that as small multi-functional molecules, maleic anhydride (MAH) and styrene, were employed the compatibility between these polymers were increased considerably. MAH and styrene were first grafted onto the ends of PPS to form an oligomeric chain of poly(MAH-co-styrene). Subsequently, the anhydride group of MAH was reacted with the terminal amino group of PA12. In these cases, FTIR spectrometry analysis indicated a high quantity of interfacial chain linkages between these polymers. Improvement of compatibility between PPS and PA12 as a result of in-situ grafting reactions were evidence from dynamic mechanical analysis (DMA), differential scanning calorimetry (DSC), rheometric analysis and scanning electronic microscopy (SEM).
