To improve the mechanical properties and to reduce the water sorption amount of denture base resins, the polymerization characteristics of three novel fluoro-substituted monomers (MAF-TBN, MAF-MAE, MAF-TBN) and three styrene-type monomers (PTBS, PEES, PACS) were studied, as well as the copolymerization of these monomers with MMA. Subsequently, the mechanical properties and water sorption of the copolymers prepared from these monomers and MMA were evaluated. The polymerization reactivity of the monomers by BPO was lower than MMA, except for PACS. However, the copolymerization reactivity of the monomers with MMA was good, except for MAF-TBN. The copolymer of MAF-MAE and MMA in three fluoro-substituted monomers and PACS and MMA in three styrene-type monomers showed similar mechanical properties and extremely low water sorption compared with those of PMMA.
为了改善义齿基托树脂的机械性能并降低其吸水量，研究了三种新型氟取代单体（MAF-TBN、MAF-MAE、MAF-TBN）和三种苯乙烯型单体（PTBS、PEES、PACS）的聚合特性，以及这些单体与甲基丙烯酸甲酯（MMA）的共聚反应。随后，对由这些单体与MMA制备的共聚物的机械性能和吸水性进行了评估。除PACS外，通过过氧化苯甲酰（BPO）引发的单体聚合反应活性低于MMA。然而，除MAF-TBN外，单体与MMA的共聚反应活性良好。与聚甲基丙烯酸甲酯（PMMA）相比，三种氟取代单体中的MAF-MAE与MMA的共聚物以及三种苯乙烯型单体中的PACS与MMA的共聚物表现出相似的机械性能和极低的吸水性。
