Abstract:Methyl-terminated allyl polyether was obtained using allyl alcohol polyether, sodium hydroxide solution and chloromethane as raw materials, and an external circulating spray reactor was used. The synthesis process of methyl-terminated allyl polyether was optimized including alkylation reagent, reactant ratio, reaction temperature and reaction time. Under the optimized conditions, the double bond retention rate reached 98.3% and the sealing rate of the product reached 98.1%. The reactivity of the product was studied, and the product had high hydrosilylation activity, short cleaning time, and the silicon hydrogen conversion rate reached 98.4%. The product is of high quality and low cost, which is suitable for industrial production. |
Key words:allyl alcohol polyether; sealing rate; double bond retention; silicone oil modifier |
