Abstract: In a previous paper,2 the authors described dimethyl 4-aminophthalate and certain of its acyl derivatives. The present article deals with the free acid, its salts, and various other derivatives or experiments not reported in the earlier paper.The literature on the subject of the free 4-amino-o-phthalic acid is meagre and confusing.Miller3 subjected 4-nitrophthalic acid to the action of tin and hydrochloric acid. The reduction proceeded smoothly, no carbon dioxide was evolved, and presumably the double salt of … Show more

“…Polyimide was first reported in 1908 by Bogert and Renshaw [93], who described the intermolecular melt polycondensation of 4-aminophthalic anhydride. Other early synthesis involved the reaction of aromatic tetracarboxylic acids or dianhydrides, such as pyromellitic dianhydride or diester diacid with diamines [94].…”

“…Polyimide, especial aromatic polyimide, has been studied since 1908 when it was prepared by Bogert and Renshaw the first time. In the 1960s, Dupont Co. invented Kapton polyimide film and obtained a series of patents on polyimide .…”

“…16,17 The introduction of the fluorine into polymers can affect many properties, in technologically desired directions. This includes higher thermal stability, 18 low moisture absorption, 19 optical transparencies, and low dielectric constant. 20 The increase of the solubility by the introduction of bulky pendant group into the polymer backbone 21 such as 5-t-butyl isophthalic acid is also reported.…”
