A composition with asymmetric structure obtained by mixing an achiral polymer having an aromatic ring in its side chain with an optically active dopant molecule; and a process for producing the same. There is provided a composition excelling in chiral discrimination capability and solvolysis resistance that can be easily obtained without the use of cumbersome asymmetric anionic polymerization technique; and provided an easy process for producing the composition. L'invention concerne une composition ayant une structure asymétrique obtenue par mélange d'un polymère achiral dont la chaîne latérale comporte un cycle aromatique avec une molécule de dopant optiquement active ; et un procédé de fabrication de cette composition. La composition selon l'invention présente une excellente capacité de discrimination chirale et de résistance à la solvolyse, et peut être obtenue de manière simple, sans nécessiter l'utilisation d'une technique maladroite de polymérisation anionique asymétrique. Le procédé selon l'invention permet d'obtenir la composition de manière simple.
