Heat-polymerized denture base materials with the cross-linking agent 1,4-BDMA and with different amounts of the cross-linking agent EGDMA have similar flexural properties. At the relatively low loading rate of 2 N/minute all the heat-polymerized denture base materials investigated have better flexural properties than the autopolymerized pour- and dough-type materials. The autopolymerized materials with the cross-linking agent 1,4-BDMA have flexural properties intermediate to the heat-polymerized and the autopolymerized resins with the cross-linking agent EGDMA. The various autopolymerized resins behave differently, probably due to varying amounts of pendant methacrylate groups. Due to so-called solvent crazing, denture base polymers have poorer flexural properties when tested in water than in air.
含有交联剂1,4 - 丁二醇甲基丙烯酸酯（1,4 - BDMA）以及不同用量交联剂乙二醇二甲基丙烯酸酯（EGDMA）的热聚合义齿基托材料具有相似的挠曲性能。在2 N/分钟的相对低加载速率下，所有研究的热聚合义齿基托材料的挠曲性能均优于自凝灌注型和面团型材料。含有交联剂1,4 - BDMA的自凝材料的挠曲性能介于含有交联剂EGDMA的热聚合树脂和自凝树脂之间。各种自凝树脂表现不同，可能是由于侧甲基丙烯酸酯基团的含量不同。由于所谓的溶剂银纹现象，义齿基托聚合物在水中测试时的挠曲性能比在空气中测试时要差。
