FIELD: agriculture.
SUBSTANCE: invention relates to antimicrobial product having at least one surface and antimicrobial polymer noncovalently connected at least to part of specified surface, being a linear and/or branched polymer, comprising atoms of nitrogen, modified polymer of precursor polymer, where specified precursor polymer is selected from group of polymers, having the following common formulas from I to III and their copolymers: 
formula I; 
formula II; 
formula III, where R1 and R2 are independently selected from linear or branched (C1-C6) hydrocarbon chain; x is in the range from 0 to 1; or where specified precursor polymer is selected from group, which consists of polymers, having the following common formulas 
Ila, 
II b, 
IIIa and 
III b, where n represents integer number in the range from 0 to 6; R4 is selected from direct link and linear or branched (C1-C6) hydrocarbon chain; R5 is selected from hydrogen and linear or branched (C1-C6) hydrocarbon chain; R6 is selected from direct link and linear or branched (C1-C6) hydrocarbon chain; and Ar7 is a nitrogen-containing heteroaromatic group; and where specified precursor polymer is modified so that at least part of specified atoms of nitrogen is substituted by substitute selected from group, which consists of linear or branched C1-C20-alkyls, and at least part of nitrogen atoms in specified precursor polymer is quarternised, besides extent of substitution of specified quarternised atoms of nitrogen makes from 10 to 100%. Surface is arranged in the form of fibres, particles, textile articles, nonwoven articles, films, filters and their combinations, and also from polymers, rubbers, glass, metals, ceramics, wood, cotton and their combinations.
EFFECT: invention makes it possible to avoid special modification of surface and to simplify method of product making, and also to preserve antivirus effect after its flushing.
