Hydrogen bonding interaction in the blends of polyamide 612 (PA 612 )/ethylene vinyl alcohol copolymer (EVOH) and the effect of the hydrogen bonds on the characterization of PA 612 /EVOH were investigated. Fourier transform infrared spectra (FTIR) analysis indicated that the interactions between the carbonyl groups of PA 612 and hydroxyl groups of EVOH increase as the content of EVOH in PA 612 /EVOH specimens increase. This interaction between PA 612 and EVOH leads to their miscibility to some extent in the amorphous region and even some effects on their crystal phase, respectively. Further isothermal crystallization behavior of PA 612 /EVOH indicates that the hydrogen bonding between PA 612 and EVOH leading difficulty in crystallization of PA 612 . Several kinetics equations are employed to describe the effects of EVOH on the crystallization properties of PA 612 in PA 612 /EVOH blends in detail. © 2011 Wiley Periodicals, Inc.
