Strength enhancement of packaging paper using nitrogen compounds

Abstract

Nitrogen-containing compounds were synthesized for the first time in the department of chemical processing of wood. These polymers, which contain amino and amidogroups, different water solubility, regularity and linearity. The essence of obtaining nitrogen compounds studied based on the chemical interaction with rosin diethylenetriamine and adipic (fumaric) acid. Amino and amidogroups participate in the formation of additional strengthening ties. The tests of samples of paper containing his compositions containing compounds, have shown that the new synthesized polymers exhibit strengthening effect similar to the effect of import connections Maresin and Melapret.
