    摘要： A method for the production of an alkylene oxide based polymer in which an alkylene oxide based polymer is obtained by allowing a monomer including one or two or more oxirane compound(s), which may have a substituent, as an essential raw material to be polymerized using a polymerization catalyst while agitating in a solvent. In this method for the production, the solvent includes one or two or more compound(s) selected from the group consisting of ketones, ketone derivatives, esters, ethers, nitrile compounds and organic halogen compounds.

    摘要： 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).
