Thermophysical properties of epoxy-polysiloxane composites of cationic polymerization

Epoxy-polysiloxane composites of cationic polymerization were synthesized based on epoxy resin and tetraethoxysilane. The thermophysical properties of the resulting polymers were studied. It was established that, as the filler content increases from 0.5 to 3 wt %, the molecular weight of an intermodal segment increases and the cross-linking density of an epoxy matrix and glass transition point reduce. The resulting polymers have a heterogeneous structure in which the regions of structuring with the corresponding glass transition points are segregated.
