C9 Petroleum Resin Modification
- Jul 06, 2017 -

With the development of modern science and technology, especially the analysis of technology progress, petroleum resin developed into a competitive era of technology. Foreign manufacturers taking full account of economic, technical, environmental and other factors on the basis of focusing on enhancing product performance and broadening the scope of application of the product. C9 petroleum resin modified along two main directions: choose a special item or modification and C9 fractions was prepared, namely, chemical modification of resin polymerization and its hydrogenation, namely hydrogenation modification.

Chemical modification

By introducing polar groups in the C9 resins can improve its compatibility with the polar compounds, dispersion, the product can be used as a stabilizer, thickener. For example: resins modified with maleic anhydride, to preparation of water-soluble resin: phenolic compounds are easy to combine Nitro arenes hydrocarbon polymers of ethylene, using phenol as solvent-catalyst, improving the polarity of the resin, mixed with other resins dispersed.

Hydrogenation modification

Common C9 petroleum resin is generally Brown or Brown, to a large extent restricted its application. Resin bond that existed were destroyed by hydrogenation, form a single bond, resin is colorless, odorless, and can also improve its weather resistance, adhesion, stability and performance, further broadened its areas of application. This will be the focus of future development in the field of petroleum resins.
