With the increasing importance of environmental protection, adhesives and coatings and other products in the water-based type of continuous improvement. As an effective tackifier, petroleum resin has a new requirement, that is, the original is a solid petroleum resin emulsion, to improve the rubber type, acrylic adhesive adhesive properties. Water-based emulsion of petroleum resin is a branch products. However, due to the C-9 petroleum resin synthesis of many raw materials, the polymerization between the complex, coupled with the factory production process separation accuracy and polymerization purity of the difference, making the composition of the petroleum resin is more complex and very unstable, so that it is necessary to conduct a series of tests on the chemical structure of the macromolecule chains of petroleum resins before emulsifying or chemically modifying raw materials with different grades from different manufacturers.
Infrared spectroscopy is one of the most effective methods to identify the functional groups of the compounds and analyze the molecular structure. The wavelength of the infrared absorption band and the intensity of the absorption band reflect the molecular structure, which can be used to identify the structure of the unknown GC /MS is the preferred method of GC qualitative, especially for the analysis of complex samples. It can give the molecular structure information of the corresponding chromatographic peaks, and also can be used for quantitative analysis to predict the measured and the molecular shape of the molecular chain.
