ABSTRACT The present invention relates to co- polymers based on unsaturated carboxylic acids and sugars capable of forming enolates, obtainable by copolymerizing the unsaturated carboxylic acids in an amount of from 35 to 80%, based on the total monomers, with an alkaline solution of at least one of palatinose and leucrose in the presence of free radical initiators at temperatures of between 60°C and 110°C, while at least one of the two monomers is continuously supplied, then cooled and precipitated by acidification. The copolymers of the present invention are excellently suitable as sequestrants, complexants and co-builders in washing and cleaning agents.
