ABSTRACT:
A process is provided for producing polyhexamethylenimine by condensing hexamethylenediamine at 50.degree. to 300.degree. C. in the presence of a palladium catalyst. The process yields substantially linear, high-molecular-weight polyhexamethylenimines, especially novel polyhexamethylenimines having a molecular weight of at least 1,000. Polyhexamethylenimines having a molecular weight of at least 500 are useful as gelling agents for organic liquids.
