SULPHONATED COPOLYMER AND METHOD FOR CLEANING SURFACES AND/OR PROVIDING SAME WITH STAIN RESISTANT PROPERTIES AND/OR FOR FACILITATING STAIN AND SOIL RELEASE |
摘要 |
A water-soluble or water-dispersible copolymer comprising:at least one polyoxyalkylene (POA) unit; andat least one sulfonated polyamide (PAS) unit;the quantity of SO3M functions, expressed as the mass of SO3- function, in said (PAS) unit or units is such that it represents at least 0.1% of the total mass of said copolymer;the total (POA) units/total (PAS) units mass ratio is 95/5 to 30/70/the number of amine functions -NH2 present in said copolymer is at most 80 milliequivalents per kilogram of copolymer;the number of carboxyl functions -COOH present in said copolymer is at least 80 milliequivalents, preferably at least 100 milliequivalents per kilogram of copolymers. |
