Abstract

It is known that Polyamide 6 absorbs water in its amorphous phase. The exact composition of the amorphous phase will determine the uptake process. The heterogeneity in the amorphous phase with respect to plasticization by water uptake is quantified in this paper using NMR relaxometry. It is shown that water occupies and plasticizes only a small part (~6%) of the nylon matrix. This part is located in between the crystalline domains where polymer chain mobility is higher. At low moisture content (
