Modification of Aliphatic Petroleum Resin by Peracetic Acid

This work demonstrates the possibility of obtaining modified aliphatic resin (PRC5) by means of petroleum resin oxidation by peracetic acid. We have experimentally determined oxidation conditions that lead to producing resin with maximum epoxy and acid numbers. Ratio of «oxidative system: PRC5» is 0.5:1, process duration is 2 hours. The modified resin structure is determined by IR and NMR spectroscopy.
