    • 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)。

    • There are provided a process for obtaining a polymer having hydroxyl groups at both terminals easily and with cheap cost and excellent efficiency from a wide variety of vinyl-based compounds, a composition containing said polymer and its use, and a polymer derived from said composition and its use.The polymerization reaction of a vinyl-based monomer (b) is carried out by using a radical polymerization initiator (c) in the presence of a compound (a) represented by the general formula:HO--A--(S).sub.x --B--OH (I)and, a polymer having hydroxyl groups at both terminals is obtained under conditions that, in the above reaction, any compound other than (a), (b) and (c) is not practically used and the compound (a) always exists in 50 mole times or more of the initiator (c) in the course of reaction in a reactor; and either a composition containing this polymer or a polymer derived from this composition is used.
