A systematic study for the structures and properties of phosphorylated pulp fibers prepared under various conditions

A bleached softwood kraft pulp was phosphorylated with (NH 4 ) 2 HPO 4 and urea at 150 ℃ for 0‒40 min, and the structures and properties of the resulting phosphorylated pulps were systematically investigated for the first time in terms of reaction time and the amount of (NH 4 ) 2 HPO 4 added. The ph...
