Chemistry of aminimides

“…72 The product from the second (CH3)3N-NH2 X" -(CH3)3N-ÑH 47 48 method is the parent compound which is hygroscopic and unstable. The other two methods give the aminimine coordinated with lithium bromide (49) and 2 mol of ferfbutyl alcohol, respectively (50).…”

“…Polymeric products containing either pendant isocyanate or ethylene-urea groups obtained from pendant aminimides have been shown to be useful in shrink-proofing woolen and worsted fabrics.146, 147 Application of aminimides of long-chain fatty acids to cellulosic fabrics like rayon or cotton makes these materials water repellent. 50 Dialkyl-/3-hydroxyalkylamine-acrylimides are useful as fabric softening agents.148 F. Surface Coatings Aminimides as precursors of isocyanates have found uses in the field of surface coatings.149 Polymers prepared from a mixture of vinyl monomers such as styrene, acrylonitrile, or acrylates and aminimides from methacrylic acid have been used in heat-cured thermoset coatings. Formulations of this type cure at 300°F or higher without the addition of melamine, epoxies, or other cross-linked agents.…”
