1,3,5-Benzenetrisamide based nucleating agents for poly(vinylidene fluoride)

Self-Nucleation of Crystalline Phases Within Homopolymers, Polymer Blends, Copolymers, and Nanocomposites

“…The standard cooling scan shows the formation of equal amounts of α-and γ-polymorphism. The authors studied the SN behavior from 122 to 160 C. The relative amount of α-and γ-crystals was determined by WAXS. In the DSC heating scans, the lower temperature melting peak corresponds to the fusion of γ-crystals, whereas the high temperature peak corresponds to the fusion of α-crystals.…”

Supramolecular Nucleating Agents for Poly(butylene terephthalate) Based on 1,3,5‐Benzenetrisamides

“…The latter is also limiting their use as additives for high melting semi‐crystalline polymers 5. 1,3,5‐Benzenetrisamide derivatives represent an alternative class of nucleating agents avoiding the mentioned drawbacks and showing remarkable nucleation effects in i‐PP6–9 and poly(vinylidene fluoride) (PVDF) 10. Owing to their amide moieties, these compounds can establish intermolecular forces via hydrogen bonds resulting in one‐dimensional columnar self‐assemblies.…”

“…Herein we report on 1,3,5‐benzenetrisamides as supramolecular nucleating agents for PBT. To evaluate structurally different 1,3,5‐benzenetrisamides as potential nucleating agents, a screening method described by Abraham and Schmidt10 for PVDF was adapted for PBT. Promising compounds were investigated in a concentration range from 0.006 wt% (60 ppm) to 0.8 wt% (8000 ppm) and compared with respect to their dissolution and crystallization behavior of the additive in the PBT melt and the crystallization temperature of PBT.…”

Influence of different beta-nucleating agents on the morphology of isotactic polypropylene and their toughening effectiveness

“…The synthesis and characterization were described in detail elsewhere [28e31]. They have been used as nucleation agents for iPP [24] and PVDF [32] and as supramolecular nanofibers [33,34]. As a reference alpha-nucleating agent, the commercially available nucleation agent, Irgaclear XT386 (alpha NA; supplier: BASF SE) and as a reference beta-nucleating agent (beta Ref), the commercially available nucleating agent, NJStar NU-100 (N,N-dicyclohexyl-2,6-naphthalene dicarboxamide, supplier: New Japan Chemical Co) were used as received.…”
