One of them was mixed with polycarbonate (PC) in a Brabender mixer. The other one was prepared in solution with the block copolymer as the interfacial agent. The blends were analyzed by 13C nuclear magnetic resonance techniques at solid state, such as: magic angle spinning (MAS); cross-polarization MAS, and variable contact time experiment. It was observed that the addition of PC in the nylon 6/PPO system causes a hardening of it, which can be attributed to strong links, like a hydrogen bond. The ideal quantity of block copolymer added to a blend to improve the compatibility is between 5 and 10%. An increase of the quantity of this agent probably makes it act as a third component. Therefore, both PC and block copolymer can be used as an interfacial agent for nylon 6/PPO blends in an ideal composition. © 1997 John Wiley & Sons, Inc.
