FIELD: chemistry.
SUBSTANCE: invention concerns application of polymerisates containing thermoplastic polymers, as filtering auxiliary and/or stabilising substances, and method of water fluid filtration and/or stabilisation. Water fluid filtration and/or stabilisation uses polymerisate in the form of polymer powder containing the following components, wt %: (a) 20 to 95 of at least one thermoplastic polyolefin and polyamide polymer, and (b) 80 to 5 of at least one substance selected out of group including silicates, carbonates, oxides, silica gel, kieselguhr, diatomite earth and linked polyvinyllactams and their mixes. Polymer powder is obtained by compounding of thermoplastic polymer (a) and substance (b) in extruder with physical and/or chemical interaction.
EFFECT: adjustable absorption by the use of insoluble, recoverable, chemically inert, slightly inflating polymerisates with large surface area.
