SUSTAINABLE ADSORBABLE POLYMERS Russian patent published in 2017 - IPC C09C1/02 D21H17/24 D21H17/26 D21H17/69 

FIELD: chemistry.

SUBSTANCE: invention relates to an aqueous suspension of mineral pigment materials with high content of solid substances, containing dispersing substances and/or dispersants based on renewable sources, as well as methods of preparing such a suspension and to use thereof. Aqueous suspension contains mineral pigment material and at least one modified polysaccharide having carboxylation degree within range of 0.6 to 2.0 and characteristic viscosity in range of 3 to 300 ml/g, where carbon of at least one modified polysaccharide exhibits rate of nuclear transformation of ¹⁴C to ¹⁴N in range of 400 to 890 transformations per hour per gram of carbon, where at least one modified polysaccharide is present in an amount of 0.05 wt% to 5.0 wt% in relation to total weight of solid substances in suspension, Brookfield viscosity of aqueous suspension ranges from 50 to 1,500 MPa⋅s at 20 °C, and content of solid substances in suspension is more than 50 to 82 wt% in relation to total weight of suspension. Modified polysaccharide is used as a dispersing substance and/or dispersant.

EFFECT: aqueous suspension is used in production of paper, plastic, paint, food products, fodder, pharmaceutical products, drinking water and/or in agriculture for reducing effect of sunlight and ultraviolet radiation on plant leaves.
