Two liquid monomers (CT-AL and CT-ACR) were synthesized from the acylation of tert-butyl catechol with different acid chlorides. The monomers were used to prepare photopolymerizable dental composite for completely replacing TEGDMA. Properties such as flexural strength, modulus of elasticity, degree of double bond conversion, polymerization shrinkage, as well as the polymerization stress were studied. Also, color alteration, translucency, and cytotoxicity were evaluated. The results show that the experimental materials formulated with CT-AL and CT-ACR have similar mechanical properties to a control material formulated with BisGMA/TEGDMA, similar polymerization shrinkage, and less polymerization stress. The composite formulated with the CT-AL monomer shows a similar degree of conversion (72%), while the composite formulated with the CT-ACR monomer has a degree of conversion lower (58%) than the control resin (71%). These results suggest that both monomers could have potential applications in the formulation of composites for dental restorations.

通过叔丁基邻苯二酚与不同酰氯的酰化反应合成了两种液体单体（CT-AL和CT-ACR）。该单体用于制备可光聚合的牙科复合材料，以完全替代TEGDMA。研究了诸如弯曲强度，弹性模量，双键转化度，聚合收缩率以及聚合应力等性质。此外，评估了颜色变化，半透明性和细胞毒性。结果表明，用CT-AL和CT-ACR配制的实验材料与用BisGMA / TEGDMA配制的对照材料具有相似的机械性能，相似的聚合收缩率和较小的聚合应力。用CT-AL单体配制的复合材料具有相似的转化率（72％），而由CT-ACR单体配制的复合材料的转化率（58％）低于对照树脂（71％）。这些结果表明，两种单体都可能在牙修复体复合材料的配方中具有潜在的应用。
