| abstract |
The invention relates to a polysaccharide-g-polyether dispersant represented as a compound of Formula 1 or a mixture of compounds of Formula (I) and Formula (II) wherein, T is the backbone polymer and is a residue of a modified cellulose or chitosan, with a molecular weight of 500 -1000,000 g/mol; A and B are each, independently, -O- or -NH-; R is linear or branched -(C1-C50alkylene)-, arylene, cyclo-C5-C8-alkylene, isophoronediyl, or linear or branched -(C2-C10alkylene)- which is interrupted by phenylene or cyclohexanediyl; P is the residue of a polyether and/or polyester chain with molecular weight between 100 and 10,000 g/mol, n is a number of 1 - 5000. |
