Measurement of Molecular Weight of Chitosan and its Degradations

TANG Zhen-xing~1, SHI Lu-er~2,YI Yu~2 (1.College of Chemical Engineering and Materials Science,Zhejiang University of Technology,Hangzhou 310014,China; 2.College of Pharmaceutical Science, Zhejiang University of Technology,Hangzhou 310014,China)  
s: As an important character in favor of knowing another chitosan character, molecular weight of chitosan and its degradations was measured in the system of CH_3COOH-NaCl through the viscosi method. Results showed [η]of chitosan degraded 4h was 187.68, the molecular weight was 250,000;[η] of chitosan was 227.32, the molecular weight was 300,000.
