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.Keywords
