摘要：
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.
