Method for gelling aqueous media, use of copolyesters as gelling agents of aqueous media and novel copolyesters for gelling aqueous media |
摘要 |
Process of gelification of aqueous medium with a copolyester oligomer comprising essentially oxyalkylenated or ocycycloalkylenated or polyoxyalkylenated dicarboxylate units at least 35 mole % of said units being similar units of which the correspondent homolymer is crystalline, at least 7 mole % of said units being bearing units of hydrophobic(s) sulfonated functions, the molecular mass in weight of said copolyesters oligomer being less than 20,000. For example: the terephtalic polyoxyethylenated sulfonated oligomers of high content of polyethyleneterephtalate. |
