    • A saturated hydrocarbon polymer terminally having a hydroxyl group is obtainable by reacting a halogen-terminated hydrocarbon polymer obtainable by cationic polymerization with a compound containing a primary hydroxyl group and an unsaturated bond. A compound obtainable by quantitatively introducing a hydroxyl group into the terminus of a saturated hydrocarbon polymer produced by living cationic polymerization is useful as a raw material of a urethane having high weathering resistance. However, until today, the reaction for obtaining the desired hydroxyl group-terminated compound by converting to an olefin terminus after completion of polymerization followed by hydroboration reaction has been known. This method requires a plurality of reaction step and thus takes time for the production. It becomes possible to obtain a saturated hydrocarbon polymer terminally having a hydroxyl group directly, without converting into an intermediate compound, by reacting a halogen-terminated hydrocarbon polymer obtainable by cationic polymerization with a compound containing a primary hydroxyl group and an unsaturated bond.
    • 末端具有羟基的饱和烃类聚合物是通过用含伯羟基的化合物和在不饱和键反应的卤素封端的烃聚合物可获得的由阳离子聚合得到的甲。 的化合物,可获得的由定量引入羟基到由活性阳离子聚合产生的饱和烃类聚合物的末端是作为具有高耐候性的聚氨酯的原料是有用的。 然而,直至今日,用于通过聚合随后加氢波拉灰反应完成后,转换为在烯烃末端获得所需的羟基封端的化合物的反应是已知的。 这种方法需要的反应步骤的多元性,因此需要花费时间的生产。 因此能够获得具有末端直接羟基的饱和烃类聚合物,不与含有伯羟基和结合到不饱和化合物转化成在中间体化合物,通过使卤素封端的烃聚合物可获得的由阳离子聚合。
