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, R⁵ are each H or a 1 to 24C substituent; R⁶, R⁷, R⁸, R⁹ and R¹⁰ are each H, an alkyl, an aryl or an aralkyl; at least two of R¹, R², R³, R⁴, R⁵, R⁶, R⁷, R⁸, R⁹ and R¹⁰ may 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.;COPYRIGHT: (C)2009,JPO&INPIT
