Determination of polymer content in styrene tar
Thread Content
What are the methods for determining the polymer content in the tar from styrene plants? Are they all enterprise standards? Are there any appropriate **standards or industry standards? I would appreciate some guidance from an expert. . . . . .
The polymer content in styrene tar is very high, and a diluted colorimetric method is generally used for a rough estimation
The tar from styrene is mainly a mixture of styrene oligomers, which used to be burned away. To analyze the composition or distribution of components in such tar, liquid chromatography or gel chromatography may be required. Additionally, its structural characteristics can be determined through mass spectrometry and infrared spectroscopy. There is little research in this area; the original poster can go to the Rubber Research Institute or the Institute of Polymer Science, Chinese Academy of Sciences for consultation.
