    • The present invention provides a novel production process for an ethylene oxide resin, in which, when the ethylene oxide resin is obtained, it is arranged that the resin should contain no antistatic agent, and further its water content is also easily controlled in not more than a definite amount, and the thermal damage of the above resin is prevented, and besides, the reduction of the cost can also be actualized. The production process for an ethylene oxide resin, according to the present invention, comprises the step of carrying out devolatilization of a solvent from a polymerization reaction liquid containing the solvent, thereby obtaining the ethylene oxide resin; with the production process being characterized by arranging that: after the devolatilization, the resin should have a solvent concentration of 0.01 to 30 weight % and a water content of not more than 200 ppm, and the resin should contain no antistatic agent.
    • 本发明提供一种新型的环氧乙烷树脂的制造方法,其中,当得到环氧乙烷树脂时,树脂不含抗静电剂,其含水量也容易控制在不超过 一定量,并且防止了上述树脂的热损伤,并且还可以实现成本的降低。 根据本发明的环氧乙烷树脂的制备方法包括从含有溶剂的聚合反应液中进行溶剂脱挥发分的步骤,得到环氧乙烷树脂; 其制造方法的特征在于:在脱挥发分后,树脂的溶剂浓度为0.01〜30重量%,水含量不大于200ppm,树脂不含抗静电剂。
