ИССЛЕДОВАНИЕ ПРОЦЕССОВ ОБРАЗОВАНИЯ ФОСФАЗЕНСОДЕРЖАЩИХ ЭПОКСИДНЫХ ОЛИГОМЕРОВ МЕТОДОМ ЛАЗЕРНОЙ МАСС-СПЕКТРОМЕТРИИ / В. В. Киреев, Ю. В. Биличенко, Р. С. Борисов и др. // Высокомолекулярные соединения. Серия Б. — 2018. — Т. 60, № 3. — С. 111–133. Рассмотрены основные особенности двух методов синтеза фосфазенсодержащих эпоксидных олиго- меров: окислением двойных связей в органоксифосфазенах и реакцией хлорциклофосфазенов с ди- фенолами и последующим взаимодействием образующихся гидроксиарилоксифосфазенов с эпихлор- гидрином. На примере гекса- и октаэвгенольных производных соответствующих циклофосфазенов установлены оптимальные условия окисления аллильных групп указанных соединений надкислотами и охарактеризованы гекса- и октаэпоксидные циклофосфазены. При эпоксидировании эвгенольных производных смеси циклофосфазенов с 3–8 фосфазогруппами отмечено протекание побочных реак- ций, приводящих к образованию связей P–OH и частичному раскрытию оксирановых циклов. Диа- новые фосфазенсодержащие олигоэпоксиды синтезированы как через стадию образования гидрок- сиарилоксициклофосфазенов и их последующего эпоксидирования реакцией с эпихлоргидрином, так и непосредственным взаимодействием хлорциклофосфазенов с избытком диана в среде эпихлор- гидрина в присутствии твердой щелочи. В последнем случае олигомеры представляют собой смеси обычного эпоксида и фосфазенсодержащих эпоксидных олигомеров с регулируемым содержанием последних в пределах до 50%. Синтезированные олигомеры содержат 1–5% фосфора и отверждаются обычными отвердителями с образованием огнестойких или негорючих композиций.

Effect of montmorillonite on polypropylene crystallization / M. L. Kerber, I. Y. Gorbunova, L. D. Shibryaeva et al. // Russian Journal of Applied Chemistry. — 2017. — Vol. 90, no. 3. — P. 435–439. The effect of additions of pure and modified montmorrilonite on the polypropylene crystallization rate was studied within the framework of Avrami model. In the presence of these fillers in amounts of 2.5–5.0 wt %, both the crystallization rate and the degree of crystallinity increase, and at the content of these fillers increased to 10% and higher values these parameters decrease. Introduction of fillers enhances the mechanical properties of polypropylene, which allows the developed material to be recommended for the production of packaging film. © 2017, Pleiades Publishing, Ltd.

Epoxy oligomers modified with epoxyphosphazenescopus / K. A. Brigadnov, Y. V. Bilichenko, V. A. Polyakov et al. // Polymer Science, Series B. — 2016. — Vol. 58, no. 5. — P. 549–555. Phosphazene-containing epoxy oligomers are obtained through a one-stage method via the interaction of hexachlorocyclotriphosphazene with an excess of diphenylolpropane in the medium of epichlorohydrin in the presence of a solid alkali. With the use of 31Р NMR and MALDI mass spectrometry, it is shown that the main components of the phosphazene fraction are penta- and tetra-aryloxysubstituted cyclotriphosphazene compounds with the corresponding numbers of epoxy groups. The maximum content of the phosphazene fraction in phosphazene-containing epoxy oligomers (∼40 wt %) is attained at a hexachlorocyclotriphosphazene-to-diphenylolpropane molar ratio of 1: 8. Phosphazene-containing epoxy oligomers cured with isomethyltetrahydrophthalic anhydride have oxygen indexes of 26–28 and are self-extinguishing. [ DOI ]
Rheological and rheokinetic properties of phosphazene-containing epoxy oligomers / I. D. Simonov-Emel’yanov, N. V. Apeksimov, L. M. Kochergina et al. // Polymer Science, Series B. — 2016. — Vol. 58, no. 2. — P. 168–172. The rheological and rheokinetic properties of a two-component binder consisting of epoxy-diane oligomers and the oligoepoxyphosphazenes PEO-1 (30 wt %) and PEO-2 (40 wt %) are studied. The viscosities of the initial oligomers at 40oC are 130 (PEO-1) and 270 (PEO-2) Pa s; the activation energies of viscous flow in the range 40–70oC are from 122 to 128 kJ/mol. The addition of equivalent amounts of curing agents, such as triethylenetetramine or iso-methyltetrahydrophthalic anhydride, reduces the initial viscosity of a composition, most strongly in the presence of the second curing agent (by a factor of 50–100). The activation energies of the cure process with triethylenetetramine in the range 45–95oC are 89 (PEO-1) and 125 (PEO-2) kJ/mol, and the gelation time at 55oC is 6 min for both oligomers. The time of gelation for the system PEO–iso-methyltetrahydrophthalic anhydride at 90oC is 475 min, and the glass-transition temperatures of the cured compositions are 238 (PEO-1) and 250oC (PEO-2), as evidenced by thermomechanical studies.

Gorlov et al. // Polymer Science, Series B. — 2015. — Vol. 57, no. 5. — P. 444–450. Triethoxysilylphosphazenes have been synthesized via hydrosilylation of cyclotriphosphazenes with various contents of 4-allyl-2-methoxyphenoxy groups by triethoxysilane at an equimolar phosphazene–silane ratio. Hydrolytic copolycondensation of the latter compounds with ?-methacryloxypropyltrimethoxysilane resulted in oligosiloxanes involving functional methacrylic and phosphazene fragments. The oligomers have been used as additives to a dental composition based on bisphenol A-diglycidyl methacrylate and triethylene glycol dimethacrylate. The modified filled compositions are characterized by reduced (4-fold) sensitivity to external illumination and improved strength properties and microhardness. © 2015, Pleiades Publishing, Ltd.

Filatov et al. // Polymer Science, Series B. — 2011. — Vol. 53, no. 7-8. — P. 412–419. Oligo(aryloxyphosphazenes) are synthesized on the basis of diphenylolpropane and hexachlorocyclotriphosphazene via the phenolate method. Corresponding functional derivatives are obtained through treatment of the oligomers with methacryloyl chloride, glycidyl methacrylate, and epichlorohydrin. GPC data indicate that modification is accompanied by an increase in the molecular mass of the oligomers. Epoxidation of a specially synthesized hexaallyloxy derivative of oligo(aryloxycyclotriphosphazene) with m-chloroperbenzoic acid proceeds incompletely to yield an oligomer with a content of epoxy groups below 6%.
