Depending on the initial ratio of HCP:resorcinol, PERO contains from 20 to 50 wt.% phosphazene component (2.0\u20134.8% of phosphorus) and have an epoxy group content up to 30 %. Products are characterized using 1H and 31P NMR spectroscopy, MALDI-TOF mass spectrometry, and elemental analysis. According to mass spectrometry, the phosphazene fractions of PERO include up to 30 individual compounds with a predominance of cyclotriphosphazenes with one unsubstituted chlorine atom and four or five glycidyl groups. PERO has a lower viscosity in comparison with similar resins based on bisphenol A, which can simplify their use as a binder for polymer composites, adhesives, and paints.<\/jats:p>","DOI":"10.3390\/polym11040614","type":"journal-article","created":{"date-parts":[[2019,4,4]],"date-time":"2019-04-04T03:13:42Z","timestamp":1554347622000},"page":"614","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Synthesis of Resorcinol-Based Phosphazene-Containing Epoxy Oligomers"],"prefix":"10.3390","volume":"11","author":[{"given":"Igor A.","family":"Sarychev","sequence":"first","affiliation":[{"name":"Mendeleev University of Chemical Technology of Russia, Miusskaya sq. 9, 125047 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Igor S.","family":"Sirotin","sequence":"additional","affiliation":[{"name":"Mendeleev University of Chemical Technology of Russia, Miusskaya sq. 9, 125047 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roman S.","family":"Borisov","sequence":"additional","affiliation":[{"name":"Topchiev Institute of Petrochemical Synthesis, Russian Academy of Sciences, Leninskii pr. 29, 119991 Moscow, Russia"},{"name":"Peoples\u2019 Friendship University of Russia, Miklukho-Maklaya str.6, 117198 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianxin","family":"Mu","sequence":"additional","affiliation":[{"name":"College of Chemistry, Jilin University, 2699 Qianjin Street, Changchun 130012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Irina B.","family":"Sokolskaya","sequence":"additional","affiliation":[{"name":"State Research Institute of Chemistry and Technology of Organoelement Compounds, sh.
