Abstract
Fylolflex oligo(resorsinol phenyl phosphate) with terminal phenyl groups is an effective plasticizer for an epoxy polymer, allowing the development of compounds with enhanced levels of physicomechanical properties, heat resistance, softening point, an flame resistance. Introduction of chromite, a cheap and active filler, into the epoxy polymer in amounts of 0.1 and 100 wt parts enhances the physicochemical and mechanical properties of the composite. Namely, the Vicat softening point increases from 132 to 140–250°С, the degradation onset temperature increases, and the yield of carbonized structures increases from 54 to 68–86 wt %, which leads to a decrease in the release of volatile pyrolysis products into the gas phase and in the combustibility of the epoxy composite.
