文摘
- •
Carboxymethyl chitins synthesized homogeneously in the green aqueous solution.
- •
Less deacetylation and degradation and higher yield than heterogeneous method.
- •
Simultaneous determination of DA, DS and carboxymethylation fraction at C3 and C6.
- •
Carboxymethyl chitins with lower DS exhibited thermo- and pH-sensitive behaviors.
- •
Potential bioapplications as injectable degradable hydrogels due to the nontoxicity.
