Epoxidation of poly-isobutylene was synthesized with petroleum ether as the solvent using per-oxy formic acid oxidant and poly isobutylene as the reactive. All factors affecting the yield of the products were investigated. The result showed that the optimum technological conditions were determined with the mass ratio of poly-isobutylene to peroxy acid oxidant specified at 1:1 . 3 . The 0 . 5 times amount of petrole-um ether was used for poly-isobutylene and the dropping process temperature was holded at 35 ℃. After dropping,the reaction was proceeded 4 h at 55 ℃. The oxidation value was reached 1. 08 after distil-lation.
