Abstract
In a previous paper, we reported on the catalytic influence of polyelectrolytes in the ammonium cyanate — urea conversion (1). In the course of the study, it was found that polymers having primary and secondary amino groups, such as polyethylenimine hydrochloride (PEI.HC1) and poly(L-lysine) hydrobromide, easily react with cyanate ions to form carbamoylated polymers. In the present chapter, we report the details of the preparation of carbamoylated polyethylenimine (CPEI) and its hydrolysis product (HCPEI), their structure, viscosity behavior and the results of an exploratory study of their flocculation properties. A preliminary report was published earlier (2).
