Abraham, F.; Kress, R.; Smith, P.; Schmidt, H.-W.: A New Class of Ultra-Efficient Supramolecular Nucleating Agents for Isotactic Polypropylene, Macromolecular Chemistry and Physics, 214(1), 17-24 (2013) -- DOI: 10.1002/macp.201200487
We present a family of 2,4,6-trimethyl-1,3,5-benzenetrisamides for ultra-efficient nucle- ation of isotactic polypropylene (i-PP). On the basis of a new symmetrically substituted core, in a series of compounds, the chemical structure of peripheral substituents was systematically varied, introducing branched aliphatic, aromatic, and cycloaliphatic moi- eties. Some of these compounds were found to promote nucleation of the a-phase in i-PP at concentrations as lowas 0.00003 wt%only,while concomitantly featuring outstanding thermal properties.
