Abstract: The invention relates to a carboxylate ester of polysaccharide characterised in that it possesses ester bonds with trimellitic anhydride and is soluble in water. The polysaccharide is esterified with trimellitic anhydride and the degree of substitution of the polysaccharide lies in the range of from 0.5 to 3. The invention further relates to methods for the manufacture of these polysaccharides esters in organic solvents, in water or in an extruder or a kneader and to their use in fabric and home care formulations.

Abstract: Unsaturated compounds of formula (I): wherein: R1, R2, and R3 are each independently H or CH3; R4 is a linear or branched C1-C30-alkylene; R5 and R6 are each independently H, C1-C20-alkyl, C3-C15-cycloalkyl, aryl, —CH2—O—C1-C20-alkyl, or —CH2—O—C2-C20-alkenyl, where R5 and R6 may together form a C3-C6-alkylene; R7 is independently H,C1-C4-alkyl, or where R8 is C1-C22-alkyl or C2-C22-alkenyl; and n is an integer from 2 to 200. Mixtures and polymers including the unsaturated compounds of formula (I). A method for preparing polymers by free-radical polymerization of monomers including the unsaturated compounds of formula (I). A process for preparing polymers including polymer-analogous reactions. And polymers including compounds (I) as cement additives, grinding aids, hydraulic binder additives, concrete plasticizers, reactive plasticizers for preparing plastics, rubber, or latex, associative thickeners and antioxidants, or for preparing polyether siloxanes.
