摘要：

Protonation of polyethylenimine (PEI) has been studied by various investigators. Most studies involved potentiometric titrations with hydrochloric acid and the effect of added salts. K. J. Liu has reported the specific influence of chloride, bromide, and nitrate ions on the viscosity of solutions of protonated PEI. It has been noticed that, when a small amount of PEI is added to ammonium nitrate, gaseous ammonia is produced. No information, however, has been found concerning the quantitative basis of the reaction. The study of the quantitative nature of protonated PEI by various reagents is reported.
