3,9-BIS(DIALKYLAMINO)-2,4,8,10-TETRAOXA-3,9-DIPHOSPHA-SPIRO(5,5)UNDECANE AND STABILIZED COMPOSITION

摘要

PURPOSE: To provide the new compounds each of which has excellent stability with respect to resistance to moisture-pickup or hydrolysis on storage and is useful for stabilizing an organic polymer. ;CONSTITUTION: The compounds are those represent by the formula (each of R₁ to R₄ is a 2-ethylhexyl, 16-30C alkyl group or the like), such as 3,9-bis[di(2- ethyl-hexyl)aminol-2,4,8,10-tetraoxa-3,9-diphosphaspiro[5,5]undecane. Such a compound represented by the formula is prepared e.g. by mixing a di(hydrogenated beef tallow)amine or di(beef tallow)amine, 3,9-dichloro-2,4,8,10- tetraoxa-3,9-diphosphaspiro[5,5]undecane and triethylamine in toluene together.;COPYRIGHT: (C)1994,JPO
