シル基が導入される。If a solvent with a large chain transfer effect is used, hydroxyl groups may not be introduced at the molecular ends of the resulting vinyl chloride polymer. The above polymerization initiator is preferably used in an amount of 0.03 mol or more per 1 mol of the monomer whose main component is vinyl chloride.If it is less than 0.03 mol, the resulting vinyl chloride polymer Hydroxyl groups are not sufficiently introduced at both ends of the molecule of the polymer, and the number of polymers in which hydroxyl groups are introduced only at one end of the molecule increases, and the reactivity of the vinyl chloride polymer decreases accordingly. The polymerization temperature is determined by the degree of polymerization of the polymer to be produced, but is preferably at least a temperature at which the polymerization initiator used is half destroyed in 10 hours by decomposition. It is usually carried out at 40 to 90"C. The degree of polymerization is generally set to an appropriate value in the range of 50 to 1000 depending on the application. In addition, in the present invention, during radical polymerization, it is necessary to adjust the degree of polymerization. A chain transfer agent may be used.Using a chain transfer agent can reduce the degree of polymerization.As such a chain transfer agent, a mercapto compound containing a hydroxyl group when chain transferred, such as 2 -Mercapl
・Ethanol etc. are preferably used. (Function) According to the method of the present invention, a monomer containing vinyl chloride as a main component undergoes radical polymerization using a polymerization initiator to obtain a vinyl chloride polymer. Further, during the radical polymerization, the polymerization initiator is decomposed to generate two radicals (nitrogen is eliminated in the case of an azobis compound), and hydroxyl groups are distributed to both radicals. Then, this radical containing a hydroxyl group reacts with a monomer mainly composed of vinyl chloride to grow a free radical polymer, and as a result, one end or both ends of the molecule of the resulting vinyl chloride-based polymer Hydroxyl groups are introduced.

部導入される。In addition, when a mercapto compound containing a hydroxyl group is used as a chain transfer agent, the mercapto bond of the chain transfer agent molecule is broken, and this reacts with the free radical polymer, resulting in the formation of a vinyl chloride polymer. A portion of the hydroxyl group derived from the chain transfer agent is also introduced at one or both ends of the molecule.
