Abstract (en)
[origin: WO2013093951A1] Composition, and processes for the production and use of mixture of water soluble biopolymers, said mixture comprising an organic fraction and a mineral fraction, the organic fraction comprising polymer molecules having a molecular weight included between 5 and 500 kDalton and a polydispersion index included between 6 and 53, wherein the organic fraction contains, in % weight of dry substance, 37 <= C <= 65; 3 < N <= 7, and N and C mean nitrogen and organic carbon being distributed among the following types of carbon atoms and functional groups with the following composition expressed as molar fraction of the total organic carbon: 0.3 < Cal <= 0.6; CN <= 0.1; OMe <= 0.1; 0.3 <= OR <= 0.6; 0.02 <= OCO <= 0.08; 0.07 <= Ph <=0.30; 0.02 <= PhOH <= 0.06; PhOR/Ar <= 0.09; 0.04 <= COOH <= 0.12; CON <= 0.12; C=0 <= 0.05; and the mineral fraction contains, in % weight of dry substance, ashes <= 30; Si <= 3.0; Fe <= 0.9; Al <= 0.8;' Mg <= 1.2; Ca <= 6.5;. K <= 10; Na <= 10; Cu <= 0.03; Ni <= 0.01; Zn <= 0.05; Cr <= 0.003; Pb <= 0.01.
