A NMR (Nuclear Magnetic Resonance) Study of the Molecular Interactions and Dynamic Behavior in Polymer-Diluent Blends in the Solid State
Abstract
A study of the molecules details of the interactions between small molecule diluents and polymers was carried out using a variety of Nuclear Magnetic Resonance methods. The focus of the study was to allow a molecular level comparison with macroscopic properties (thermal and mechanical) in multicomponent polymer blends. The details of plasticization, antiplasticization diluent sorption and blend compatibility were addressed. The polymer systems studied were high impact strength engineering plastics: Polycarbonates and poly (2,6-dimethylphenyl oxide) blends with polystyrene and structural analogues of these two fundamental systems. A three fold approach was used, with experiments which probe (a) the host polymer and changes in its dynamics as a consequence of diluent addition, (b) the dynamics of the diluent itself modified by the host and (c) experiments which probe directly the intermolecular intimacy in a multicomponent glassy blend.
