This work reports quasi elastic neutron scattering (QENS) results on the tr
ehalose/water/acrylamide-acrylic acid copolymer system, recently employed i
n agricultural chemistry. H/D substitution technique allows to separate the
diffusive dynamics of trehalose from that of water. The analysis indicates
that although from a structural point of view water behaves as bulk water,
its dynamics is strongly affected by both the polymeric matrix and trehalo
