Urethane dimethacrylate (UDMA) is a monomer widely used in photopolymerization reactions to produce biomaterials, due to its advantageous properties such as mechanical resistance and relatively low viscosity. However, this monomer is expensive. Reducing the quantity of UDMA monomer required to obtain the final polymer, without losing its main properties, is essential not just in terms of costs but also green chemistry principles. It has been demonstrated that glycerol inclusion into the polymeric matrix during polymerization is one way to achieve this goal. Thus, this work proposes the insertion of glycerol and metal oxide fillers (Al₂O₃, TiO₂, Nb₂O₅, La₂O₃ and ZrO₂) in the photopolymerization of urethane dimethacrylate, with the aim to study how these effects the degree of conversion, as well as the thermal properties of the final polymer. The thermal properties were evaluated using simultaneous thermogravimetry–differential thermal analysis (TG–DTA) and differential scanning calorimetry (DSC). The degree of conversion/rate of polymerization was calculated using mid-infrared spectroscopy (MIR). The polymers filled with Al₂O₃, TiO₂, Nb₂O₅ and La₂O₃ exhibited good conversion values of 87.42, 78.47, 77.64 and 75.51%, respectively. For all polymers synthesized, no significant changes were observed in their thermal stability. Lastly, it is suggested that the incorporation of the oxides in the monomeric mixture correlate to the degree of conversion, with scanning electronic microscopy (SEM) analysis suggesting oxide dispersion interferes with the morphology of the polymer.

氨基甲酸酯二甲基丙烯酸酯（UDMA）是一种光聚合反应中广泛用于生产生物材料的单体，这是由于其优越的性能，例如机械强度和相对较低的粘度。但是，这种单体很昂贵。在不损失其主要性能的前提下，减少获得最终聚合物所需的UDMA单体的数量不仅在成本方面，而且在绿色化学原理方面都是至关重要的。已经证明，在聚合过程中将甘油包含在聚合物基质中是实现该目标的一种方法。因此，这项工作建议插入甘油和金属氧化物填料（Al ₂ O ₃，TiO ₂，Nb ₂ O ₅，La ₂ O ₃和ZrO ₂）在氨基甲酸酯二甲基丙烯酸酯的光聚合中，目的是研究它们如何影响转化率以及最终聚合物的热性能。使用同时热重分析-差热分析（​​TG-DTA）和差示扫描量热法（DSC）评估热性能。使用中红外光谱法（MIR）计算转化率/聚合速率。填充有Al ₂ O ₃，TiO ₂，Nb ₂ O ₅和La ₂ O ₃的聚合物分别具有87.42％，78.47％，77.64％和75.51％的良好转化率。对于所有合成的聚合物，其热稳定性均未观察到明显变化。最后，建议在单体混合物中氧化物的掺入与转化率相关，扫描电子显微镜（SEM）分析表明氧化物分散会干扰聚合物的形态。
