In this work, previously synthesized biopolyols were analyzed in terms of their rheological and thermal properties, very important from the technological point of view. For better evaluation of performed synthesis, the influence of its time and temperature on the properties of biopolyols was determined. In the end, obtained materials were used to prepare rigid polyurethane-polyisocyanurate (PUR-PIR) foams, to evaluate their potential application in polymer technology. Presented results fully justified conducting of synthesis in two steps. Biopolyols obtained after second step of synthesis were characterized by two times lower viscosity than polyglycerols resulting from first step. Moreover, their thermal and oxidative stability was noticeably higher and enabled their effective incorporation into manufacturing of PUR-PIR foams. Spectroscopic and microscopic analysis confirmed that foams were successfully obtained from polyglycerols and biopolyols, however, there were noticeable differences in the mechanical performance of prepared materials. Partial substitution of petrochemical polyol with polyglycerol resulted in the decrease of compressive strength, comparing to reference sample, while incorporation of biopolyols noticeable enhanced that parameter.

在这项工作中，对先前合成的生物多元醇的流变性和热学性质进行了分析，从技术角度来看非常重要。为了更好地评估进行的合成，确定了其时间和温度对生物多元醇性能的影响。最后，将获得的材料用于制备硬质聚氨酯-聚异氰脲酸酯（PUR-PIR）泡沫，以评估其在聚合物技术中的潜在应用。提出的结果完全证明了进行两步合成的合理性。合成的第二步后获得的生物多元醇的特征是其粘度比第一步产生的聚甘油低两倍。此外，它们的热和氧化稳定性明显更高，并使其能够有效地结合到PUR-PIR泡沫塑料的生产中。光谱和显微镜分析证实，泡沫是从聚甘油和生物多元醇中成功获得的，但是，所制备材料的机械性能存在明显差异。与参考样品相比，石油化学多元醇被聚甘油部分取代导致抗压强度降低，而掺入生物多元醇则明显提高了该参数。
