It has been shown previously that high levels of residual monomer have a deleterious effect on the properties of denture base polymers. Levels of residual monomer were determined on a homopolymer and a copolymer using gas-liquid chromatography. A wide range of recommended and 'short cut' curing cycles were then investigated which produced values ranging from 0.56 to 18.46%. From the ranges examined an optimum cycle of 7 h at 70 degrees C and 1 h at 100 degrees C was established which was used to polymerize 23 currently available synthetic denture base polymers. Only small differences were found between the materials tested with a range from 0.54 to 1.08% of residual monomer.
先前已表明，高残留单体水平会对义齿基托聚合物的性能产生有害影响。使用气液色谱法测定了一种均聚物和一种共聚物中的残留单体水平。然后研究了一系列推荐的和“捷径”固化周期，其产生的值范围为0.56%至18.46%。在所研究的范围内，确定了70℃下7小时和100℃下1小时的最佳周期，该周期用于聚合23种目前可用的合成义齿基托聚合物。在所测试的材料之间仅发现了很小的差异，残留单体范围为0.54%至1.08%。
