PRODUCT AND POLLUTANT-BINDING AGENT FOR SURFACE PURIFICATION Russian patent published in 2016 - IPC C11D3/37 C11D17/04 C08F220/00 

FIELD: chemistry.

SUBSTANCE: invention relates to product for surface purification and versions of cleaning system, containing, at least, part of such product and pollutant-binding agent. Product for surface purification contains pollutant-binding agent. Pollutant-binding agent, contains polymer, with polymer containing two or more monomer units, selected from the group, consisting of: a. non-ionic monomer units, with non-ionic monomer units containing non-ionic hydrophilic monomer unit, with non-ionic hydrophilic monomer unit being derived from acrylamide; b. anionic monomer units, with anionic monomer units being derived from monomers, elected from the group, consisting of monomers, which have, at least, one carboxyl functional group; c. cationic monomer units, with cationic monomer unit, being derived from (3-methacrylamidopropyl)trimethylammonium chloride (NATMAC); and d. zwitterionic monomer units, with zwitterionic monomer units being derived from zwitterionic monomers, selected from the group, consisting of sulphobetaine monomers, phosphobetaine monomers and carboxybetaine monomers. Polymer contains, at least, one monomer unit from group a and, at least, one monomer unit, selected from groups b, c and d. At least part of product demonstrates pollutant adsorption index, at least, 75 mg, as measured in accordance with test method of pollutant adsorption. Polymer contains, at least, 69.9 wt % of monomer unit from group a, with polymer containing not more than 30.1 wt % of monomer unit, selected from group, consisting of group b, group c, group d and their mixtures.

EFFECT: obtaining product for surface purification with improved properties of pollutant adsorption in comparison with known materials.
