采用气相色谱法对24件上颌义齿中的残留单体含量进行了测定。使用时间较长的义齿，其残余单体含量较短的义齿低。丙烯酸树脂义齿中残留单体的数量随着老化而减少，可用双曲线表示。拟合曲线还表明，大部分损失可以在5年内完成;然而，残留单体含量的完全损失需要许多年。
The quantity of residual monomer content in 24 maxillary dentures was detected by gas liquid chromatography. The residual monomer contents tended to be lower in dentures used for long periods than in those used for short periods. Decreases in the quantities of residual monomer in acrylic resin dentures as a result of aging can be expressed in a hyperbola. The fitted curve also suggests that most of the loss could be accomplished in 5 years; however, complete loss of the residual monomer content takes many years.
