AN AQUEOUS EMULSION AND METHOD FOR MAKING IT

The invention relates to an aqueous emulsion of a hydrophobic anhydride-based sizing agent, prepared by homogenizing the said anhydride-based sizing agent in an aqueous phase which comprises a stabilizer, which is an anionic lignin-carbohydrate complex, where lignin and carbohydrate are covalently b...

Beschreibung
Zusammenfassung:	The invention relates to an aqueous emulsion of a hydrophobic anhydride-based sizing agent, prepared by homogenizing the said anhydride-based sizing agent in an aqueous phase which comprises a stabilizer, which is an anionic lignin-carbohydrate complex, where lignin and carbohydrate are covalently bound with each other. The invention further relates to a use of this anionic lignin-carbohydrate complex as a stabilizer as well as to a method for making an aqueous emulsion of a hydrophobic anhydride-based sizing agent.
