Light-colored hydrocarbon and terpene resins decolorized by iodine compounds

摘要

Resins prepared by cationic polymerization of pure or combined feeds of C5-C10 hydrocarbons are decolorized by use of iodine or bromine or their compounds. Activation by heat or radiation is usual. The decolorizing agents may be added prior to or during the polymerization process or to the polymerized resin before or after isolation.
