Abstract: Unsaturated dinitriles are reacted with an aromatic compound such as benzene in the presence of a Lewis acid such as aluminum chloride to yield novel aralkylenedinitriles, such as 5-methyl-5-phenylnonanedinitrile and isomers thereof. The aralkylenedinitriles can be reduced to novel aralkylenediamines or novel cycloalkylalkylenediamines. Polymerization of the aralkylenediamines or cycloalkylalkylenediamines with polycarboxylic acids provides novel polyamides of tough, clear, colorless character.
