Synthesis, characterization, and biodegradation studies of new cellulose-based polymers

Scientific Reports, 2023
New cellulose carbamates and cellulose acetate carbamates were prepared by classical addition reaction of isocyanates with alcohols. A Telomerization technique was used to make the grafted molecules strongly anchored and more hydrophobic. These molecules
