Effects of various factors on reaction rate and polymerization degree of ethylene oxide on properties of products were discussed. The IR spectroscopy and thermal stability were also discussed.
The new pigment was prepared by selection of polysaccharide and optimization of experiment condition. Then characteristic of the pigment was discussed by UV, IR and DSC.
