Morphology of reactively compatibilzed polymer blends was discussed in terms of particle asphericity (ζ)-size (a) map. Reactive melt blending of polysulfone (PSU) with polyamide 6 (PA) was carried out at 20/80 (PSU-PA) wt ratio by adding a few wt% of reactive PSUs; maleic anhydride-grafted PSU (PSU-MAH) or phthalic anhydride-terminated PSU (PSU-PhAH). Morphology development was investigated by light...
Reactive blending of dissimilar polymers involves in situ reactions of functionalized components to form a block or graft copolymer at the interface between phases. The copolymer is believed to play a role of the emulsifier to prevent particle coalescence and to improve interfacial adhesion. A mixture of non-reactive polysulfone (PSU) and small amount of reactive PSU, phthalic anhydride-terminated...
