Functionalized Oligoaryloxycyclotriphosphazenes and Noncombustible Binders Based on Them
Carboxyl-containing aryloxycyclotriphosphazene (I) has been used for curing the ED-20 epoxy resin or a phosphazene-containing epoxy oligomer. In the case of ED-20, curing occurs in the range of 125‒220°C and is accompanied by an exothermic effect that increases from 26 to 50 J/g with an increase in the amount of aryloxycyclotriphosphazene (I) from 25 to 50%. The curing of the phosphazene-containing epoxy oligomer occurs in the temperature range of 140–240°C and is accompanied by an endothermic effect (−ΔH = 6.5–6.8 J/g). Cured compositions based on ED-20 + I are self-extinguishing (flammability class V‑1 according to UL-94), and phosphazene-containing epoxy oligomer + I compositions are noncombustible (class V-0 according to UL-94) regardless of the ratio of the initial components.
期刊介绍:
Polymer Science, Series C (Selected Topics) is a journal published in collaboration with the Russian Academy of Sciences. Series C (Selected Topics) includes experimental and theoretical papers and reviews on the selected actual topics of macromolecular science chosen by the editorial board (1 issue a year). Submission is possible by invitation only. All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed
