PREPARATION PROCESS OF POLYOXYALKYLENE POLYAMINE HAVING TERMINAL SECONDARY AMINO GROUP

摘要

A process for preparing polyoxyalkylene polyamine having secondary amino groups at the end of polymer chain by reaction of polyoxyalkylene polyol with primary amine is disclosed. Polyoxyalkylene polyamine having higher content of the secondary amino groups can be obtained by using a catalyst containing (1) Ni and Zn, (2) Co and Zn, or (3) Ni, Co and Zn; by using a conventionally known catalyst in the presence of monohydric alcohol; or by using the catalyst containing (1) Ni and Zn, (2) Co and Zn, or (3) Ni, Co and Zn, in the presence of monohydric alcohol.
