## Abstract The thermal aging of polyamide 4,6 was investigated by DSC, SEM, WAXS, and ^1^H solidβstate NMR. Phase composition, chain mobility, morphology, and domain sizes were determined as a function of aging time. Proton transverse magnetization relaxation was measured at low resonance frequenc
