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 such as capture of heavy metals by forming a mercaptide. 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 such as surface size for paper, textile fiber finishing, additives for adhesives and paints, and binders for non woven textiles.
