Epoxies are often cured using primary and secondary amines in an efficient reaction catalyzed by tertiary amines. Through coordination effects, lower the transition-state energy enough to allow take place under ambient conditions. In this paper, we demonstrate how, conditions, bound close intramolecular proximity a amine able catalyze amine-epoxy reactions as well promote etherifications epoxy-...

It has been shown for the first time that cationic polyelectrolytes (weakly basic (polyamide-polyamine-epichlorohydrin resin (PPER)) and strongly (polydimethyldiallylammonium chloride (PDMDAAC) copolymer of acrylamide with methylene dimethylamminopropylacrylamide (CA MC DMAPA)), widely used in paper cardboard technology as flocculants (existing technology), additionally participate processes co...

Eighteen structurally varied amines were subjected to harsh oxidative conditions, and their stability was assessed seen in the context of biological thermal stability. Steric effects play a large role stabilization under presence carbon dioxide plays vital degradation pathway ethanolamine (MEA). Tertiary are generally very stable, known not form carbamates any extent. Many steric stabilization,...
