This research focuses on designing and synthesizing phosphorus-nitrogen-based biopolyols for use in polyurethane (PU) foam production. Polyol (ESBO-DYM) with dual functionalities, renewability, and nonflammability is synthesized through the epoxy ring-opening reaction of epoxidized soybean oil with phosphorus and nitrogen-containing tetraol products (DYM). The mechanical and flame retardant properties of PU foams with the addition of an ESBO-DYM were investigated. Increasing the amount of phosphorus in the PU foams increased the thermal stability properties. Using 100% ESBO-DYM as a polyol in the foam formulation increased the limiting oxygen index (LOI) value to 22.9% and resulted in the highest char yield according to the thermal gravimetric analysis (17% at 600 \u00b0C). Additionally, the introduction of ESBO-DYM polyol into the formulation resulted in a decrease in the compression strength of the foams. The foam density decreased as the amount of ESBO-DYM polyol in the formulation increased. The foam with the highest amount of ESBO-DYM had a foam density of 29.1 kg\/m3. The morphology of the foams was characterized using a scanning electron microscope (SEM). As a result of this study, flame retardant polyurethane foams were formulated using a renewable source, polyol, along with commercial compounds.<\/jats:p>","DOI":"10.55730\/1300-0527.3656","type":"journal-article","created":{"date-parts":[[2024,5,1]],"date-time":"2024-05-01T06:32:11Z","timestamp":1714545131000},"page":"237-250","source":"Crossref","is-referenced-by-count":1,"title":["Phosphorus and nitrogen-containing soybean oil polyols: Effect on the mechanical properties and flame retardancy of polyurethane foam"],"prefix":"10.55730","volume":"48","author":[{"given":"DEN\u0130Z","family":"\u00d6ZTA\u015eKIN","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L\u00dcTFULLAH YUSUF","family":"Y\u0130VL\u0130K","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u0130LAYDA","family":"ACARO\u011eLU DEGITZ","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"TARIK","family":"EREN","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"34691","published-online":{"date-parts":[[2024,4,25]]},"container-title":["Turkish Journal of Chemistry"],"original-title":[],"language":"en","deposited":{"date-parts":[[2026,10,21]],"date-time":"2026-10-21T12:55:44Z","timestamp":1792587344000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.tubitak.gov.tr\/chem\/vol48\/iss2\/5"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,4,25]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2024,4,25]]}},"URL":"https:\/\/doi.org\/10.55730\/1300-0527.3656","relation":{},"ISSN":["1300-0527"],"issn-type":[{"value":"1300-0527","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,4,25]]}}}
