Résumé : New 13C NMR relaxation experiments were carried out to probe the methine/methylene bond reorientational dynamics within specific microstructures. In parallel, a series of molecular dynamics experiments performed at three temperatures on isotactic (iPP) and syndiotactic (sPP) oligomers in an explicit solvent were analyzed. Experiments and simulations indicate a slight but noticeable difference between the local dynamics of meso and racemic microstructures.
