The problem of winding of a long polymer chain around an attractive rigid rod is studied in relation with the localization transition exhibited by this system. The role of chiral and polar interactions is considered. The results are compared with previous models of adsorption of a polymer and of helix-coil transition.

On étudie le problème de l'enroulement d'une longue chaîne de polymère autour d'une barre rigide, en relation avec la transition de localisation présentée par ce système. Le rôle des interactions chirales et polaires est considéré. Ces résultats sont comparés à des modèles précédemment proposés pour décrire l'adsorption d'un polymère et la transition hélice-pelote.
