The effect of molecular weight on the performance of paper strength enhancing polymers
Abstract
The influence of dextran molecular weight (77,000 to 2000,000) on the strength of fiber-fiber bonds was investigated. A series of cationic dextrans with different molecular weights, from 77,000 to 2000,000, was prepared and the adsorption behavior on fiber was characterized. The maximum amount of adsorbed dextran increased with decreasing molecular weight, while the adsorbed layer thickness on colloidal silica increased with increasing …
