摘　　要：目的研究聚合方式对义齿基托树脂中残余甲基丙烯酸甲酯含量的影响。方法按照不同的聚合方式,将实验分为3组,每组制备3块试验样块.按照YY0270-2003规定的气相色谱法实验方法测试各组样品的甲基丙烯酸甲酯单体(MMA)含量。结果不同聚合方式得到的材料中MMA的百分含量明显不同,以微波聚合方式得到的基托材料残余单体含量最低。结论聚合方式对义齿基托材料残余单体含量具有显著影响。Objective To research the influence of the content of MMA remain in denture base polymers by polymeric mode. Methods The experiment was disported in three group in term of polymeric mode, three specimen was made in every group. To test the content of MMA by GC requiment of YY0270 - 2003. Results The content of MMA in denture base polymers by different polymeric mode was different, the list was got by micro - wave initiated polymeric mode. Conclusion The content of MMA was remarkable affected by polymeric mode.
