POLYAMIDE COMPOSITION STABILIZED WITH COPPER COMPLEX AND ORGANIC HALIDE COMPOUND, STABILIZING AGENT AND METHOD FOR PREPARING COMPOSITION Russian patent published in 2004 - IPC

FIELD: organometallic chemistry. SUBSTANCE: invention describes polyamide composition comprising polyamide and stabilizing agent wherein composition comprises at least one copper complex with phosphine compound and/or mercaptobenzimidazole compound as stabilizing agent and at least one organic halide compound wherein copper amount is from 10 to 1 000 part per million, halogen amount is from 50 to 30 000 g/mln in the molar ratio copper : halogen = from 1:1 to 1:3 000. Also, invention describes stabilizing agent and method for preparing polyamide composition. Usage of new stabilizing agent as component of polyamide composition provides the enhanced stability against leakage flows, thermal stability at temperatures above 150 C and resistance to extraction also. EFFECT: improved and valuable properties of composition. 9 cl, 6 tbl, 7 ex
