Tetramines by amination of dialdehyde glycol adducts
Abstract:
A process in which a dialdehyde is reacted with a polyoxyalkylene glycol to form a dialdehyde glycol condensate which is alkoxylated with propylene oxide, butylene oxide or mixtures thereof and the resulting product is then catalytically aminated to provide, for example, a tetramine is disclosed. These compounds are useful as curing agents for epoxy resins and for reaction with isocyanates to prepare polyurea elastomers and to manufacture articles, such as automotive body panels by reaction injection molding.
