Study of the Influence of the Modification of Glass Microspheres on the Properties of Syntactic Foams Based on Oligomethylsiloxane

The dependence of the apparent density of oligomethylsiloxane–filler systems on the size of the microspheres and their bulk density was established. The acid–base method was used to determine the acid–base properties of the surface of fillers and to assess the interaction at the phase boundary.
