Abstract

We present a family of 2,4,6-trimethyl-1,3,5-benzenetrisamides for ultra-efficient nucleation 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 is systematically varied, introducing branched aliphatic, aromatic, and cycloaliphatic moieties. Some of these compounds are found to promote nucleation of the α-phase in i-PP at concentrations as low as 0.00003 wt% only, while concomitantly featuring outstanding thermal properties.
