Influences of Active Components Content on Cationic Polymerization for C9 Petroleum Resin

Related Articles

Abstract

The cationic polymerizations of pure components simulated C9 fraction were carried out in the presence of various active components in the polymerization systems. The effects of active components content on the properties of C9 petroleum resins were investigated. The C9 petroleum resins with different dicyclopentadiene content were characterized by FI-IR. The results showed that the increasing content of indene and dicyclopentadiene both improved the softening point. However, dicyclopentadiene took part in the copolymerization and introduced unsaturated double bonds into C9 resin. The thermo-oxidative degradation of unstable double bonds contributed to the color of petroleum resins.
