Embodiment 1
[0052] 1) Preparation of polyether. Add a mixture of 220g nonylphenol and 2.0g potassium hydroxide into the reactor, replace the air in the reactor with nitrogen, seal the reactor and heat it to 110°C, reduce the pressure to 2000 Pa, and evaporate the water , Introduce nitrogen into the reactor to restore normal pressure, raise the temperature to about 140°C, and continuously press 696g of propylene oxide into the reactor until the pressure does not change any more. After the reaction was completed, the reactant was cooled to room temperature, neutralized with acetic acid, and washed with water to remove the catalyst. The water and volatile matter are evaporated under reduced pressure to obtain the nonylphenol polyether product.
[0053] The chemical formula of the polyether obtained is:
[0054]
[0055] 2) Add 59g of sodium methoxide to 898g of polyether obtained in step 1) to react to generate sodium polyether alcohol, then add 76.5g of allyl chloride, the reaction tim...

[0062] 1) Preparation of polyether. Add a mixture of 220g nonylphenol and 2.0g potassium hydroxide into the reactor, replace the air in the reactor with nitrogen, seal the reactor and heat it to 110°C, reduce the pressure to 2000 Pa, and evaporate the water , feed nitrogen into the reactor to restore normal pressure, raise the temperature to about 140°C, and continuously press 864g of butylene oxide into the reactor until the pressure does not change any more. After the reaction was completed, the reactant was cooled to room temperature, neutralized with acetic acid, and washed with water to remove the catalyst. The water and volatile matter are evaporated under reduced pressure to obtain the nonylphenol polyether product.
[0063]
[0064] 2) Add 44g of sodium hydroxide to 1066g of polyether obtained in step 1) to react to generate sodium polyether alcohol, then add 76.5g of allyl chloride, the reaction time is 2-10h, and the reaction temperature is 50-150°C. After the r...

[0071] 1) Preparation of polyether. Add a mixture of 220g nonylphenol and 2.0g potassium hydroxide into the reactor, replace the air in the reactor with nitrogen, seal the reactor and heat it to 110°C, reduce the pressure to 2000 Pa, and evaporate the water , Introduce nitrogen into the reactor to restore normal pressure, raise the temperature to about 140°C, and continuously press 696g of propylene oxide into the reactor until the pressure does not change any more. After the reaction was completed, the reactant was cooled to room temperature, neutralized with acetic acid, and washed with water to remove the catalyst. Moisture and volatile matter are evaporated under reduced pressure to obtain the nonylphenol polyether product.
[0072]
[0073] 2) Add 59g of sodium methylate to 898g of polyether obtained in step 1) to react to generate sodium polyether alcohol, then add 103.5g of 5-chloro-1,3-pentadiene, the reaction time is 2-10h, the reaction temperature At 50-150°C, a...
