Abstract: Based on the structure of 2-methy-2，5-dioxo-1，2-oxaphospholane（OP）which are cyclic estolide structure，and the ring can be opened through hydrolysis or alcoholysis，studies the reaction feasibility，solidification process and flame retardancy of OP/hydroquinone/epoxy preformed polymer；successfully prepares the epoxy containing phosphorus，the epoxy has good flame retardancy after solidifing 12 h，the limited oxygen index is 25.7%，the calmet burning test reaches UL 94 V-0 grade.

Key words: epoxy, 2-methy-2, 5-dioxo-1, 2-oxaphospholane, hydroquinone, flame retardancy
