A Flame retardant polyether ester urethane was produced using PPG, phosphorous, phthalic anhydride, and isophorone diisocyanate. For the formulation of polymer blend (PBs), bio-based polyurethane was procured from castor oil (CPU) and was blended with polyether ester urethane (PEEU). The different characterizations were done to determine the effect of bio based polyurethane on the properties of PEEU. The comparative studies show PBs have better properties compared to flame retardant PEEU. The thermal degradation study shows a 30–40% decrease in the rate of thermal degradation in PBs. LOI values of PBs have been decreased by 2–3%. The mechanical properties show that the breaking elongation of PBs has increased with 50–90%, but on the other hand, tensile strength has been decreased from 3 (MPa) to 5 (MPa). The gel content in PBs has increased with 10–20%. The hydrolytic stability and contact angle of PBs have been increased with an increase in the CPU ratio. Soil burial test results show that increasing the ratio of CPU in PBs lowers the rate of bacterial attack on the polymeric chain.

使用PPG，磷，邻苯二甲酸酐和异佛尔酮二异氰酸酯生产了阻燃性聚醚酯氨基甲酸酯。为了配制聚合物共混物（PBs），从蓖麻油（CPU）中采购生物基聚氨酯，并将其与聚醚酯氨基甲酸酯（PEEU）混合。进行了不同的表征，以确定生物基聚氨酯对PEEU性能的影响。比较研究表明，与阻燃PEEU相比，PB具有更好的性能。热降解研究表明，PB中的热降解率降低了30–40％。PB的LOI值已降低2-3％。力学性能表明，PB的断裂伸长率增加了50-90％，但另一方面，抗张强度却从3（MPa）降低到5（MPa）。PB中的凝胶含量增加了10–20％。PB的水解稳定性和接触角随着CPU比率的增加而增加。土壤埋藏测试结果表明，增加PB中CPU的比例会降低细菌对聚合物链的侵袭率。
