Studies on the cationization of agarose

Cationized agaroses with different degrees of substitution (0.04-0.77) were synthesized, employing 3-chloro-2-hydroxypropyltrimethylammonium chloride (CHPTAC). The influence of different reaction parameters on the substitution degree and molecular weight was evaluated. The investigated parameters we...
