METHOD OF PRODUCING COMPOSITIONS OF ARYLDITHIOPHOSPHONIC ACID POLYESTERS AND AMMONIUM SALTS THEREOF FROM HYPER-BRANCHED POLYESTER-POLYOLS, ARYLDITHIOPHOSPHONIC ACID POLYESTER COMPOSITIIONS AND AMMONIUM SALTS THEREOF, HAVING ANTICORROSION ACTIVITY

摘要

FIELD: chemistry. ^ SUBSTANCE: invention relates to novel compositions of polyesters of formula (Ia-c), ammonium salts thereof and synthesis method thereof. The compositions can be used as soft steel corrosion inhibitors. n=2-4; X=H (Ia, I), NH4 (); . The method involves reaction of hyper-branched polyester-polyol with c 2,4-bis(3,5-ditertbutyl-4-hydroxyphenyl)-1,3,2,4-dithiadiphosphethane-2,4-disulphide or 2,4-bis(4-phenoxyphenyl)-1,3,2,4-dithiadiphosphethane-2,4-disulphide in molar ratio 1:16 in conditions given in the claim. ^ EFFECT: high anticorrosion activity of the compounds. ^ 4 cl, 3 ex, 1 tbl
