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) Diamine
Both main components of mischmetall could potentially serve as highly coordinating metals for asymmetric diamine
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.
