Cellulose from paper pulp was alkalizated with NaOH 30% then carboxymethylated with monochloroacetic acid gave carboxymethyl cellulose (CMC). CMC resins then alkalizated again with NaOH 30% gave sodium carboxymethyl cellulose (Na-CMC) before esterification/amination reaction With epichlorohidrin/ethylendiamine. Esterification/amination reaction with epichlorohidrin/ethylendiamine was carried out in two step too: in the first step, Na-CMC was reacted with epichlorohidrin, and in the second step, 2-oxiranylmethyl carboxymethyl cellulose reacted with ethylendiamine gave selulose-g-epichlorohidrin/ethylendiamine. FT-IR spectroscopy analysis indicated C-N amine vibration in the region 1417 cm-1 and in the 1600cm-1 region attributed to vibration of C=O group. Morphological analysis using SEM showed homogeneous and porous at their structure.
