FIELD: organic chemistry.
SUBSTANCE: invention relates to a process for the preparation of amidomethylated vinyl aromatic bead polymers. The method for producing amidomethylated vinyl aromatic bead polymerizates consists in the interaction of at least one vinyl aromatic bead polymerizate with at least one compound of the formula
, in which R1 and R2 are two carbon atoms of an aromatic ring with six carbon atoms, and at least one condensed formaldehyde, in the presence of at least one protic acid and at least one compound of the formula H(3-n)C(Br)nR3 in which R3 is Br or bromoalkyl with 1–4 carbon atoms and n is 1.
EFFECT: method makes it possible to efficiently obtain amidomethylated bead polymers in high yield, taking into account environmental problems.
