LIGHT SCATTERING OF POLYSACCHARIDE FROM LACQUER IN AQUEOUS SOLUTION
The polysaccharide having weight-average molecular weight Mw=1. 09×105, isolated from the sap of lac trees （Vietnam）, was separated into 12 fractions by aqueous-phase preparative gel permeation chromatography. The molecular weights and molecular weight distributions of the fractions were measured in...

| description | The polysaccharide having weight-average molecular weight Mw=1. 09×105, isolated from the sap of lac trees （Vietnam）, was separated into 12 fractions by aqueous-phase preparative gel permeation chromatography. The molecular weights and molecular weight distributions of the fractions were measured in aqueous 0.08M KCl/0.01 M NaAc and 0.4M KCl/0.05M NaAc at pH =7. 6 by light scattering, viscometry and gel permeation chromatography. The Mark-Houwink equation in aqueous 0.08M KCl/0.01M NaAc at 30℃was found to be [η]= 2.28×10-2 Mw0.52 （cm3/g）, which indicated the polysaccharide chain in the aqueous solution to be a spherical random coil. |
