摘要： The present invention relates to a polymer having a thiol group at one end of the molecule which is obtained by subjecting the monomers capable of radical polymerization to radical polymerization in the presence of a thiolcarboxylic acid and then treating the resulting polymer with an alkali or acid; to a process for producing the same; and to a block copolymer based on the polymer having a thiol group at the end. The polymer having a thiol group at one end is difficult of forming disulfide linkages by oxidation and thus difficult of becoming insoluble. it is also a highly reactive material that will find wide use in varied application areas. The block copolymer based on the polymer having a thiol group at the end is superior in compatibility and will find wide use in varied application areas.

摘要： The present invention provides a process for producing easily on an industrial scale a polyvinyl ester having a high degree of polymerization and PVA having a high degree of polymerization derived by saponification from such a polyvinyl ester. The process of this invention makes it possible to produce the desired product especially even when the polymerization is carried out until a high conversion to polymer is attained, as well as even when the polymerization is terminated while the conversion to polymer is still low.
