Polysulfone-Nylon 6 block copolymers were synthesized by the interaction of chloro-terminated polysulfone and liquid caprolactam with sodium metal as condensation agent.Block copolymers were characterized by solubility characteristics
infrared spectro-seopy
dynamic mechanical behavior and differential thermal analysis.The presence of the polysulfone block reduced the water sensitivity of homopoly-mer Nylon 6.
