本研究的目的是研究在软质丙烯酸树脂材料中使用不同的增塑剂，以减少增塑剂的浸出，从而增加组织调理剂的耐久性。制备含有三种类型的聚合物/共聚物粉末和四种类型的增塑剂液体（DEHM、迪巴、DAA和DINA）的不同组合的样品。使用动态力学分析仪在水浸之后测量每个样品的动态粘弹性。还测量了吸水率、溶解度和重量变化。在动态粘弹性、吸水率和溶解性方面，发现材料之间存在显著差异。含有P-n-BMA的样品在整个浸泡过程中具有最稳定的G'和G“得分。P-n-BMA与DEHM一起作为组织调理剂的最合适的液体组分是最合适的粉末。这些结果表明，有可能通过组合不同的聚合物和增塑剂来改善组织调理剂的耐久性。
The purpose of this study was to investigate the use of different plasticizers in soft acrylic resin materials to reduce leaching of the plasticizer and thus increase the durability of tissue conditioners. Samples were prepared containing different combinations of three types of polymer/copolymer powder and four types of plasticizer liquid (DEHM, DIBA, DAA and DINA). The dynamic viscoelasticity of each sample was measured after water immersion using a dynamic mechanical analyzer. Water absorption, solubility and weight change were also measured. A significant difference was found among the materials regarding dynamic viscoelasticity, water absorption and solubility. The samples containing P-n-BMA had the most stable G' and G"scores throughout the immersion. P-n-BMA is the most suitable powder together with DEHM as the most suitable liquid component for a tissue conditioner. These results suggest that it is possible to improve the durability of tissue conditioners by combining different polymers and plasticizers.
