The crosslinking reaction of a triglyceride derivative containing alpha,beta-unsaturated ketones with diaminodiphenylmethane via aza-Michael addition has been extensively studied. First, a model study with monofunctional Compounds showed that the conjugated addition product undergoes a series of transformations leading to formation of a substituted quinoline. The proposed reaction pathway is presented as a variation of the Skraup-Doebner-Von Miller quinoline synthesis. The presence of quinolines as crosslinking points in the cured materials has been proved by means of different characterization techniques, and the properties derived from this aromatization process have been described. This new crosslinking approach has been successfully applied to an aldehyde-containing triglyceride to obtain quinoline-containing thermosets. (C) 2010 Wiley Periodicals, Inc.
