The stability at the onset temperature represents a relation between the lengths of the different aliphatic
diamines in the repeat unit versus the temperature [5, 10].
Here, we are comparing
diamines with similar rigidity and functionality, so differences in Shore D development will be dependent primarily on the reaction rate.
Synthesis and antikinetoplastid activity of a series of N,N'-substituted
diamines. Bioorg Med Chem Lett.
reported the siloxane containing
diamine as curing agent for DGEBA.
Bulab tertiary amine catalysts are based on TMEDA (tetramethylethylene
diamine).
Synthesis of Heteroaromatic
Diamines (4, 4'-(l, l'-[l, 4-(2, 6-Anthryl)Bis(4-Phenyl)-4'Pyridyl])-Bis(lH-l,2J-Triazole-4, 1 -Diyl-Methoxy)
DiamineBoth main components of mischmetall could potentially serve as highly coordinating metals for asymmetric
diamine synthesis:
Similarly, the other two PBz precursors were synthesized by using the
diamines [1,4-diaminobutane (1.76 g, 0.02 m) and tetraethylenepentamine (3.8 mL, 0.02 m)] instead of ethylene
diamine.
* Yse-Cure is based on spiroacetal, a heterocyclic
diamine. The 16 grades are designed for two-component, room-temperature curing systems.
This article discusses the dielectric spectroscopy and some optical properties of semi-alicyclic polyimide thin films obtained from 5-(2,5-dioxotetrahydrofurfuryl)-3-methyl-3-cyclohexene-1,2-dicarboxylic acid anhydride (DOCDA) and bicyclo[2.2.2]oct-7-ene-2,3,5,6- tetracar-boxylic dianhydride (BOCA) and two aromatic
diamines: 4,4'-oxydianiline (ODA) and bis[4-4-(aminophenoxy) phe-nyl]sulfone (p-BAPS).
Quinone diimines are unlike phenylene
diamines in their effects on vulcanization characteristics.
