Features of modification of polyaminoamides with rosin-maleic adducts

The features of the process chemical modification polyaminoamides based on adipic acid and diethylenetriamine with rosin-maleic adducts differing in content maleopimaric (8.55; 16.46 31.12 % wt.) are considered. Modification amount equal to number secondary amino groups repeating unit polymer was carried out melt at temperature 160–180 °C for 3 h under continuous stirring. controlled by monitoring change amine numbers reaction mass. most intensive different occurs within 1 h. It has been established that adduct wt. reacts degree reaches 57.39 %. structure synthesized products studied IR-spectroscopy. physicochemical properties (solubility, softening point, viscosity solutions, numbers, etc.) obtained indicate complex mixtures consist chemically modified polyaminoamides, N-substituted imides unreacted (free resin acids).
