Abstract
A process in which a polyamine initiator is oxyalkylated to form the corresponding polyamine polyoxyalkylene glycol which is then catalytically aminated to provide a polyoxyalkylenepolyamine is disclosed. These compounds are useful as curing agents for epoxy resins and for reaction with isocyanates to manufacture articles, such as automotive body panels, by reaction injection molding.
