Application features of hexane diacid polycondensation products with diethylene triamine and resin acids in paper technology

Abstract

Article examines the effectiveness of the reinforcing action for the first time received additives based on adipic acid with diethylenetriamine and tall oil rosin acids rosin. It was found that the synthesized polymers exhibit polyaminoamide hydrophobic properties due to the presence in their structure of resin acids . Strengthening effect of these compoundsis shown by introducing the structure of nitrogencontaining groups contribute to the formation of additional interfiber bonds. Tests have paper samples containing in their composition nitrogen compounds showed that hardening effect new synthesized polymers are not inferior to imported compound Melapret PAE / A, and hydrophobicity and the wet paper samples with the newly synthesized polymers exceed the value of these indicators for the paper samples containing imported analog.
