Abstract
The synthesis of carbamoylethyl ethers of an arabinogalactan by the O-alkylation reaction of alcohols with acrylamide in the presence of caustic soda has been investigated. It has been shown that pronounced hydrolysis of the amide groups to carboxy groups takes place when the reaction is performed in solvents. If the reaction is performed in the solid phase with brief heating at 125°C, no appreciable hydrolysis of the amide groups is observed but the formation of the ether is accompanied by degradation of the polysaccharide itself.
