Production method 1
Polymerize glycerol and refined propylene oxide under the catalysis of potassium hydroxide at a temperature of ~℃ and pressure. Then lower the temperature to ~℃, press the material into the neutralization kettle, add water under stirring to neutralize the excess potassium hydroxide, add phosphoric acid at ~℃ to neutralize to ~℃, then slowly raise the temperature to ~℃, vacuum dehydrate and filter.
Production method two is produced by the addition reaction of propylene glycol polymer and water.
