Probing self-assembled 1,3,5-benzenetrisamides in isotactic polypropylene by C-13 DQ solid-state NMR spectroscopy

Using C-13 double quantum solid-state NMR spectroscopy, we were able to observe nuclei of a supramolecular BTA based additive on the nanoscale in a matrix of i-PP at a concentration of only 0.09 wt%. These nuclei exhibit the analogous structural features as the crystalline phase of the neat additive.
