FIELD: chemistry.
SUBSTANCE: disclosed are copolymers based on N-vinylpyrrolidone, having as terminal fragments a cyanovaleric acid residue and a hydrogen atom, having general formula (I) 
where the monomer link is a 4-vinylpyridine (4-VP) fragment, if X is 
or a 2-methyl-5-vinylpyridine (2-M-5-VP) fragment, if X is 
, wherein the content of monomer links which are 4-VP or 2-M-5-VP fragments is 20-90 mol%; the viscosity-average molecular weight Mµ of the copolymers is equal to 10-350 kDa, and the acid number is equal to (0.1-5.6)·10-3 mg KOH/g. Also disclosed is use of said copolymers as an anti-pneumoconiosis agent.
EFFECT: high efficiency of using the compound.
