LOW POLYMERIZATION DEGREE POLYSACCHARIDE DERIVATIVE AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polysaccharide derivative having a low polymerization degree and a low acetylation degree. SOLUTION: The present invention provides a low polymerization degree polysaccharide derivative represented by formula (1), wherein R1, R2, R3, R4, R5are each H or a 1 to 24C substituent; R6, R7, R8, R9and R10are each H, an alkyl, an aryl or an aralkyl; at least two of R1, R2, R3, R4, R5, R6, R7, R8, R9and R10may be bound to each other to form a ring together with the adjacent one or more atoms; (n) is a natural number, and having an average polymerization degree of 20 to 80, and a total acetyl substitution degree of≥1.7 and <2.6.
