An acrylic-modified polyolefin type ionomer (Ion., Zn 2⫹), was successfully applied to compatibilize poly(ethylene terephthalate) (PET)/ polyamide-6 (PA-6) blends. Melt-mixed blends were prepared at various PET/PA-6 ratios and at constant main component ratio, with various amounts of Ion., Zn 2⫹. The techniques applied to characterize compatibilization were tensile testing, dynamic mechanical analysis, d.s.c. and morphology of cryofractured and etched specimens using electron microscopy (SEM). The effects of thermal history and physical ageing were also examined. Compatibilization was attained at Ion., Zn 2⫹ levels higher than 10 wt%. Good tensile and impact properties were obtained in quenched blends, while in annealed samples crystallization of main components reduced ductility drastically.
