(4-HYDROXY-3,5-DI-TERTIARY-BUTYLPHENYL)-PROPIONIC ACID SALTS AS STABILIZING AGENT OF POLYVINYL CHLORIDES AND METHOD OF THEIR SYNTHESIS Russian patent published in 2000 - IPC

Abstract RU 2150463 C1

FIELD: organometallic chemistry, chemical technology. SUBSTANCE: invention relates to the novel compounds, namely, (4-hydroxy-3,5-di-tert.-butylphenyl)-propionic acid salts of the general formula: where R is C(CH3)3; Me is metal taken among the group: Zn, Ba, Ca, Cd, Al, Sn, Mg, Cr+3, Mn+2; n is metal valency and n = 2-4. Compounds can be used as stabilizing agents for polymers and additional agents to oils. The goal of invention is synthesis of the novel (4-hydroxy-3,5-di-tert. -butylphenol)-propionic acid salts that is attained by synthesis of the novel chemical substance of the above given formula. EFFECT: new substance, broadened assortment of thermostabilizing agents. 3 cl, 9 tbl, 30 ex
