| titleOfInvention | Anionic polysaccharide derivative |
| abstract | The invention provides an anionic polysaccharide derivative. The structural general formula of the derivative is [A(B)m(Q)n(D)o(E)p(F)q]i, wherein A is a polysaccharide unit, B is a carboxylic acid group taking methylene as a bridge foundation, Q is a carboxylic acid group taking a triazine ring as the bridge foundation, D is a sulfoacid group taking the triazine ring as the bridge foundation, E is a carboxylic acid group taking an ester bond as a bridge foundation, F is a crosslinking agent for the anionic polysaccharide derivative; m, n, o and p are the degree of substitution, q is the degree of crosslinking, m is more than or equal to 0 and less than 3, n is more than 0 and less than 3, o is more than or equal to 0 and less than 3, p is more than or equal to 0 and less than 3, q is more than or equal to 0 and less than 3, the sum of m, n, o, q and q is more than 0 and less than or equal to 3, and m, o and p cannot be zero simultaneously; and i is the degree of polysaccharide ring polymerization, and is an integer of between 10 and 1,000,000. The anionic polysaccharide generates an anionic polysaccharide derivative by a compound reaction of polysaccharide and 2 to 4 types of anion-containing groups, while an anionic polysaccharide crosslinking derivative is prepared by a reaction of the anionic polysaccharide derivative and a crosslinking agent or a reaction of crosslink polysaccharide and an anionic compound. Due to the electro-negativity and viscosity of anions of the product, the anionic polysaccharide derivative is a universal high-efficiency flocculating agent and a viscosity regulating agent, and has a wide application prospect. |
