Polyarylate (PAR)-nylon 6 block copolymers of various block lengths were prepared by the anionic polymerization of e-caprolactam using the polymeric activator from hydroxy-difunctional PAR and toluene diisocyanate. Phase-separated morphology of PAR-nylon 6 block copolymer was observed by transmission electron microscopy and the thermal properties were measured by differential scanning calorimetry (d.s.c.). Partial miscibility between PAR and nylon 6 segments was more evident with shorter constituent blocks. In binary blends of PAR or nylon 6 with PAR-nylon 6 block copolymer, molecular-level mixing of homopolymers with corresponding blocks of block copolymer was supposed from the thermal properties measured by d.s.c.
