| 摘 要： | 考察了乳液中挥发性单体的气液相平衡规律,发现在单体浓度小时,平衡气相单体浓度与液相浓度呈线性关系。利用这种线形关系,建立了用顶空气相色谱技术分析乳胶中挥发成分含量的方法,可以准确、快速地测定各类乳胶中挥发性成分的含量。

| Abstract: | Gas-liquid phase balance law of volatile monomers in emulsion was investigated revealing a linear relationbetween balanced gas phase monomers concentration and liquid phase concentration when monomers concentration waslow. This linear relation was used to set up an approach by witch volatile content in latex could be analyzed with static head-space gas chromatography. The approach was precise and rapid. |

| Keywords: | Static Head-Space Gas Chromatography emulsion volatile content |
