A process for efficiently producing a polymer hydroxylated at both terminals from a variety of vinyl monomers readily at a low cost, which comprises polymerizing a vinyl monomer (b) by using a radical polymerization initiator (c) in the presence of a compound (a) represented by the general formula HO-A-(S)x-B-OH in such a manner that the reaction system is substantially free from any reactants other than the components (a), (b) and (c), and the amount of the component (a) present in the reaction vessel is at least 50 times by mole as large as that of the component (c) throughout the reaction.
一种利用各种乙烯基单体以低成本高效生产两端羟基化的聚合物的工艺,该工艺包括在通式 HO-A-(S)x-B-OH 所代表的化合物(a)存在下,通过使用自由基聚合引发剂(c)使乙烯基单体(b)聚合,反应体系中除组分(a)、(b)和(c)外基本上不含任何反应物,并且在整个反应过程中,反应容器中组分(a)的存在量至少是组分(c)的 50 倍(摩尔)、(b)和(c)以外的任何反应物,并且在整个反应过程中,反应容器中存在的组分(a)的量至少是组分(c)的 50 倍(按摩尔计)。
