Polymers of Phenyldiacetylenes – Functional Thermostable Additions to Industrial Resins

Abstract

High thermal and thermooxidation stability of homo and copolymers of diphenyldiacetylene and p-diethynylbenzene was established. The amount of coke residue, obtained from commercial epoxy-resins, is essentially increased upon their modification with added polymers. Additions of polydiethynylbenzene to commercial olygoetheracrylates improved their thermooxidation stability.

Synthesis of homo‐ and copolymers of para‐diethynylbenzene in the presence of the cobalt carbonyl ‐ diphenylbutadiyne complex

“…Depending on the catalyst used, it may have intramolecular branched or cross‐linked structures, [6–8] including those with phenylene fragments [9,10] . Polydiethynylbenzene (PDEB), which has a different structure, for example, has been studied as an insoluble super‐crosslinked material with a micro/mesoporous structure, [11,12] as a thin‐film material for dry lithography, [13] as a modifier of industrial resins and oligoesteracrylates, [14] in the creation of humidity sensors, [15] in the creation of cobalt‐organic complexes and soft ferromagnets, [6,16,17] as a part of ablation material [18,19] and composites, [20] in the development of materials with photoluminescence, electroluminescence and nonlinear optical properties [21] …”
