Xylan is a highly available polysaccharide in the plant kingdom and is therefore a valuable resource for novel materials from renewable resources. Hydroxyalkylation is one of the most common reactions to derivatize biopolymers by altering hydroxyl groups. State of the art procedures incorporate epoxides, which are toxic, carcinogenic and highly explosive. In this study, hydroxyalkylation with propylene...
A novel amphiphilic biopolymer was synthesized by incorporating hydrophobic segment cholic acid (CA) into hydrophilic segment carboxymethyl xylan (CX) through coupling agent. Structural characteristics and self-assembly behaviors of the amphiphilic conjugates in aqueous solution were investigated in detail. Results showed that the conjugates provided monodispersed self-assembled micelles in distilled...
The development of modified fillers is one of the most promising research outcomes that address the challenges of papermaking such as reduced production cost, improved optical properties, better formation and improved drainage rate. In the present investigation, an attempt has been made to evaluate the interaction of xylan with precipitated calcium carbonate (PCC) through adsorption process with an...
The levelling-off degree of polymerization (LODP) is typically considered an apodictic number of each cellulosic source that relates to the length of its cellulose crystallites. In this study, we have performed hydrothermal and alkaline treatments on bleached birch kraft pulp to adjust the xylan content, and the resulting pulps have been subjected to acid hydrolysis to determine their LODP. The results...
