摘要: Abstract The phase-transfer catalytic epoxidation of hydroxyl-terminated polybutadiene (HTPB) by hydrogen peroxide was investigated using quaternary ammonium salts, tungstate hydrate and phosphoric acid as the catalyst cocatalysts, respectively. influences amount Aliquat 336 peroxide, molar ratio to (PO 4 3− /WO 2− ), pH value organic solvents on conversion double bonds in HTPB polymer were studied detail. kinetic also discussed apparent activated energy for estimated be 21.04 kJ/mol.
