    • This invention provides a process by which a polymer having a hydroxyl group at both terminals can be easily obtained with a cheap price and good efficiency from a wide field of vinyl-based monomers including polar ones. The process is arranged in such a manner that the polymerization of a vinyl-based monomer (a) is performed in the presence of an alcohol (b) having no addition-polymerization reactivity by using an initiator (c) consisting essentially of a peroxide and, on this occasion, at least one of catalysts (d) selected from a group consisting of an organic sulfonic acid compound having no addition-polymerization reactivity and an inorganic acid is further used and a reactor does not substantially contain any component other than the (a), (b), (c) and (d).
    • 本发明提供了一种方法,通过该方法可以从包括极性的乙烯基类单体的广泛领域以便宜的价格和良好的效率容易地获得两端具有羟基的聚合物。 该方法以乙烯基类单体(a)的聚合方式通过使用基本上由过氧化物组成的引发剂(c)在不具有加聚反应性的醇(b)的存在下进行, 在这种情况下,进一步使用选自不具有加聚反应性的有机磺酸化合物和无机酸的催化剂(d)中的至少一种,并且反应器基本上不含除( a),(b),(c)和(d)。

    • 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。
