WebMar 12, 2024 · Nevertheless, the high inherent wettability often hinders its advancement in becoming an efficient substitute in packaging industry. ... The degree of deacetylation (DDA), polymer molecular mass and viscosity of the deacetylated raw resource were continuously monitored with time until the maximum DDA was reached. Web4.1 The inherent viscosity is determined by measuring the flow time of a solution of known polymer concentration and the flow time of the pure solvent in a capillary viscometer at a fixed temperature. The inherent viscosity value is calculated from the flow time values. 5. Significance and Use 5.1 The inherent viscosity is relatable to the ...
