Synthesis and antikinetoplastid activity of a series of N,N'-substituted
diamines.
This study presented the synthesis of a series of some novel epoxy-amine polymers by the polymerization of DGEBA with the aromatic
diamines bearing long alkyl chains and ether linkages.
First, involvement of a flexible co-monomer DOCDA reduces the polyimide chain--chain interaction and disrupts the interaction with the aromatic moieties of ODA or p-BAPS
diamines.
Simple coating formulations were made by dissolving 10 g of the epoxidized polymer and a stoichometric amount of
diamine (2.
Similarly, the n(N-H) stretching vibration of
diamines were not detected in the IR spectra of expected [Ni(PDTC)(
diamines)]+ indicating the absence of
diamines in these complexes.
The
diamines 9,9'-BAFL and 3,4'-diaminodiphenyl ether (3,4'-ODA) were used as received.
The relatively small-sized cells obtained with
diamine (TDA and EDA) implies that gelling reactions are catalyzed by the initiator amine during the foaming process as urethane forming reactions are catalyzed by amine.
With different
diamine ratios, as the activity and chemical structure of the two
diamines are different, polymerization processes are different and the molecular chains would have different binding patterns and terminal groups.
Under the hood of modern automobiles, where long-term stability at 150[degrees]C is desired, the semiaromatic polyamides, mostly polyphthalamides of aliphatic
diamines and phthalic acids, compete with metals.
Quinone diimines are unlike phenylene
diamines in their effects on vulcanization characteristics.
This work deals with the amidation of PET at high temperatures to the polyphthalamide PA6T (poly [iminoterephtaloyliminohexane-1,6-diyl]) and derivatives thereof by
diamines DA (Scheme 1).
Ethacure - These are room temperature liquid substituted aromatic
diamines.
