Lubricants are widely used in thermoplastic polymers to increase the overall rate of processing or to improve surface release properties. Because of the low level of lubricants normally used in a polymer, it may not be possible to analyze the additive directly by common spectroscopic or thermal chemical techniques. However, lubricants as well as other additives in the polymer can be qualitatively analyzed by pyrolysis-gas chromatography (Py-GC) after extraction. In this work, several lubricants have been studied to demonstrate that Py-GC is a viable tool to investigate lubricants. The advantages of using Py-GC in the analysis of lubricant have also been discussed.
润滑剂广泛应用于热塑性聚合物中，以提高整体加工速率或改善表面脱模性能。由于聚合物中通常使用的润滑剂含量较低，可能无法通过常规光谱或热化学技术直接分析该添加剂。然而，聚合物中的润滑剂以及其他添加剂在萃取后可通过热解气相色谱法（Py-GC）进行定性分析。在这项工作中，对几种润滑剂进行了研究，以证明Py-GC是研究润滑剂的一种可行工具。还讨论了在润滑剂分析中使用Py-GC的优点。
