Filed:

Apr 3, 2007
Appl. No.:

12/293496
Inventors:

Arthur G. Mack - Prairieville LA, US
Hoover B. Chew - Prairieville LA, US
Assignee:

ALBEMARLE CORPORATION - Baton Rouge LA
International Classification:

C09K 21/14
C08J 9/02
C09K 3/00
US Classification:

521107, 524710, 2521823
Abstract:

Improved flame retardant additives are formed from (A) at least one bis(alkanoic acid ester) of a ring-brominated aromatic diester diol; (B) liquid alkylated triphenyl phosphate having an approximate average formula (RPhO)P═O) in which each R is, independently, a hydrogen atom or a Calkyl group and x is an average number in the range of about 0.2 to 3; and (C) at least one alicyclic phosphonate ester having 1, 2 or 3 phosphorus atoms in the molecule, at least one of which is part of an alicyclic ring system, and having a phosphorus content of at least about 15 wt %. Combinations of these components are well-suited for use in various polymers or resins, especially polyurethanes.

C09K 21/12
US Classification:

442136, 521 85, 252609
Abstract:

This invention relates to a phosphorus flame retardant composition formed from bringing together components comprising: a) a cyclic phosphanate flame retardant comprising (5-ethyl-2-methyl-2-oxido-1,3,2-dioxaphosphorinan-5-yl)methyl methyl ester of P-alkylphosphonic acid, and bis[(5-ethyl-2-methyI-2-oxido-1,3,2-dioxaphosphorinan-5-yl)methyl]ester of P-alkylphosphonic acid; and b) an alkylated triaryl phosphate ester flame retardant having a triphenyl phosphate (TTP) content of less than about 1 wt % based on the total weight of the alkylated triaryl phosphate ester. This invention further relates to the use of this phosphorus flame retardant composition especially for in polyurethane foams and textile applications.
