Abstract: Effects of chemicals and temperature on color of polymerized rosin were investigated.The results showed that the chelating agent and oxalic acid exhibited a good washing performance in reducing color of the rosin. The Gardner color of the polymerized rosin produced in a factory with chelating agent was reduced for one grade.

Key words: polymerized rosin, purification, color
