Abstract EN
Papermaking has been using high quantities of retention agents, mainly cationic substances and organic compounds such as polyamines.
The addition of these agents is related to economic and environmental issues, increasing contamination of the effluents.
The aim of this work is to develop a cationic polymer for papermaking purposes based on the utilization of alpha-cellulose.
The cationization of mercerized alpha-cellulose with 3-chloro-2-hydroxypropyltrimethylammonium chloride (CHPTAC) is governed by a pseudo-second-order reaction.
The initial amorphous fraction of cellulose is reacted with CHPTAC until the equilibrium value of nitrogen substitution is reached.
Nitrogen is incorporated as a quaternary ammonium group in the polymer.
Also, the kinetic constant increased with decreasing crystallinity index, showing the importance of the previous alkalization stage.
The use of modified natural polysaccharides is a sustainable alternative to synthetic, nonbiodegradable polyelectrolytes and thus is desirable with a view to developing new products and new processes.
