| Abstract: | A kind of low-polymeric organic phosphate flame retardantwas synthesized by a modified preparation using P2O5, dimethyl methyl phosphonate （DMMP）and ethylene glycol as precursors, and stannous octoate as catalyst. IR technique was used to characterize its chemical structure. Examining the reaction conditions showed that when n（DMMP） ： n （ P2O5 ） = 1.5： 1, reaction temperature keeping at 80 - 90℃, reaction time keeping at 2- 4 h. Under the above conditions,synthetic productivity can reach 93.8%. The color and viscosity of the product can be well controlled by adding ethanol to the rehosphate, flamaction. |
