Abstract
AbstractThe effect ob substituted groups in hydroxyethyl starches with variable degrees of substitution on the conformation of starch molecules was investigated by the infrared and X‐ray analysis. The highest substitution with alkoxyl groups caused the shifting of the equatorial anomeric groups of glucose units to the axial position due to strain effect in the rings of monomers. The X‐ray analysis showed that the volume of unit cell of starch was increased 4.3% with the highest substitution of corn starch. This improved the penetration of dye molecules in the coating of textiles.
