synthetic approach to symmetrical diamino-substituted Troger's base analogues, allowing the synthesis of 1,7-, and 4,10-diamino derivatives with no additional substituents and of 3,9-diamino derivative with methyl groups in the 1-, 4-, 7- and 10-positions. The synthesis uses regioselective nitration of dihalo-substituted- or tetrahalo-substituted Troger'sbases followed either by hydrogenation of the nitro
A process for producing an aryl carbamate of a high purity at a high yield by reacting a diaryl carbonate with an amine compound having one or more hydrogen atoms bonded to the N position in the presence of carboxylic acid(s) of the following general formulae (I): R1-COOH and/or (II): R2-COOH (wherein R1 represents an alkyl or cycloalkyl group having a carbon atom at the α-position, which is bonded to only one hydrogen atom, and R2 represents an alkyl group having a carbon atom at the α-position, which is not bonded to a hydrogen atom).

A polymer compound is formed by condensing a polyacrylic acid, a polyfunctional amine represented by the following general formula (1), and an aromatic monoamine. A chain structure constituted by the polyacrylic acid has free carboxyl groups and carboxyl groups to which the aromatic monoamines are bonded.
Y is a straight-chain alkyl group having 1 to 4 carbon atoms, a phenylene group, or an oxygen atom. R1 and R2 are each independently one or more hydrogen atoms, a methyl group, an ethyl group, a trifluoromethyl group, or a methoxy group.

Disclosed is a method for preparing a polyglutarimide by reacting an acrylic resin with an imidizing agent. The method uses a superficial fluid, preferably supercritical carbon dioxide’ to remove unreacted materials and by-products, and thus can provide a polyglutarimide having excellent optical properties.
