چکیده
Submitted: Jul 13, 2013; Accepted: Aug 26, 2013; Published: Aug 29, 2013 Abstract: Two new arylene diamines compounds have been synthesized via palladium-catalyzed reaction of 1,4-phenylenediamine with two aromatic dibromides. This one-pot reaction was based on using the catalyzed system resulting from Pd / BINAP, Pd / di-t-butylphosphinobiphenyl, Pd / P(t-Bu) , Pd / 1,3-bis(2,63 diisopropylphenyl)imidazolium chloride.

Five new aromatic poly(amide-imide)s (5a-e) were synthesized by direct polycondensationreaction of N-(4-carboxy phenyl) trimellitimide (3) with five aromatic diamines (4a-e) by usingtriphenyl phosphite in N-methyl-2-pyrrolidone (NMP) and pyridine at solution containingdissolved CaCl2. All of the polymers were obtained in quantitative yields with inherentviscosities between 0.29-0.40 dL/g. The r...

A series of novel aromatic polyamides with pendent 4,40-dimethoxy-substituted triphenylamine (TPA) units were prepared via the direct phosphorylation polycondensation from a new dicarboxylic acid monomer, N,N-bis(4-carboxyphenyl)-N0,N0-di(4-methoxyphenyl)-1,4-phenylenediamine (4), and various aromatic diamines. These polyamides were amorphous with good solubility in many organic solvents, such ...
