Abstract: 
The processes of the ED-20 diane epoxy resin structuring, containing disperse oxidic fillers and modifiers are studied with the help of the rotational viscometry method. It is shown that the acid -base interactions between the functional groups of the resin part molecules and the active centers of the fillers surface play the defining role in these processes. The structure degree is defined both by the total amount of the surface active centers, and their pKa value. It is approved that the diffusive phenomena intensity is defined by the acid force of the fillers hydroxyl groups whereas the share of the volume effects in the compositions is small.
