Abstract
The translational and rotational motion of two probes whose only difference is their ability to undergo hydrogen bonding has been examined in bulk, amorphous poly(isobutyl methacrylate) (PiBMA) films. Lophine, which can hydrogen bond with the PiBMA matrix, was found to have significantly slower translational as well as rotational mobility than s-lophine, which does not have significant interactions with PiBMA. Translational diffusion of both probes may be satisfactorily represented by Vrentas-Duda free volume theory, taking into account the interaction energy associated with hydrogen bonding for lophine. Rotational motion of lophine had a stronger temperature dependence than s-lophine.
