主　　题：regenerated cellulose cellulose oleate sonochemistry degree of substitution thermoplasticity 

摘      要：Derivatization has great potential for the high-value utilization of cellulose by enhancing its processability and ***,due to the low reactivity of natural cellulose,it remains challenging to rapidly prepare cellulose derivatives with high degrees of ***“cavitation effectof ultrasound can reduce the particle size and crystalline index of cellulose,which provides a possible method for preparing cellulose ***,a feasible method was proposed for efficiently converting regenerated cellulose to cellulose oleate with the assistance of ultrasonic *** adjusting the reaction conditions including ultrasonic intensity,feeding ratios of oleic acid,reaction time,and reaction solvent,a series of cellulose oleates with degrees of substitution ranging from 0.37 to 1.71 were ***,the effects of different reaction conditions on the chemical structures,crystalline structures,and thermal behaviors were investigated *** oleates with degrees of substitution exceeding 1.23 exhibited amorphous structures and thermoplasticity with glass transition temperatures at 159.8 to 172.6℃.This study presented a sustainable and practicable method for effectively derivatizing cellulose.
