摘　　要：背景:采用适当的方法提高材料的聚合程度,有利于改善其相应的理化性能。目的:观察二期高温、高压处理对Ceramage瓷聚体单体转化率的影响。方法:应用傅里叶变换红外色谱仪,分别测试经Solidilite聚合器固化的Ceramage体部材料和经过自控多用途树脂聚合仪在温度120℃,压力0.6MPa,时间7min条件下二次处理后的材料,在标准基线方法下得到各自的单体转化率并进行比较。结果与结论:常规处理时Ceramage体部材料的单体转化率为(72.7±2.2)%,经二期热压处理后单体转化率为(75.4±1.5)%,提高幅度为2.7%。提示二期热压处理可以显著提高Ceramage体部材料的单体转化率,从而有可能改善材料的各项性能。BACKGROUND： Using appropriate methods to improve the degree of material polymerization will help to improve material physical and chemical properties. OBJECTIVE： To study the influence of post heated and press on the monomer conversion of Ceramage ceramic optimized polymer material. METHODS： Twenty Ceramage ceramic optimized polymer material specimens, with diameter of 4 mm and thickness of 3 mm, were double-side cured in Solidilite light cure case for 90 seconds. Ten random specimens had been post heated in 120 ℃ and pressured 0.6 MPa for 7 minutes by multi-purpose resign aggregator. The samples were crushed with a hydraulic machine. The monomer conversion of Ceramage ceramic optimized polymer material was obtained under different conditions. RESULTS AND CONCLUSION： The monomer conversion of Ceramage ceramic optimized polymer material significantly increased from （72.7±2.2）% to （75.4±1.5）%, with the increasing degree of 2.7%. Post heated and press can significantly increase the monomer conversion of Ceramage ceramic optimized polymer material so as to improve material performance.
