A liquid flame retardant composition which comprises one or more flame retarding agents, which are the epoxides obtainable by reacting tetrabromobisphenol A with epichlorohydrin and their end-capped derivatives represented by Formula (1) is provided. The liquid composition is especially useful in the preparation of rigid polyurethane foams.

Flame retardant composition

Poly (pentabromobenzyl acrylate) having weight average molecular weight (Mw) in the range from 4,000 to 120,000 and polydispersity index of less than 10 as determined by high temperature gel permeation chromatography, wherein the glass transition temperature of the poly (pentabromobenzyl acrylate) is not more than 150 C.&#xb0;, the poly (pentabromobenzyl acrylate) includes chains which are terminated by an end group derived from a chain length regulator, wherein the end group is a thiol group &#x2014;SR, and wherein R, is a linear or branched alkyl group composed of not less than 8 carbon atom.

Poly (pentabromobenzyl acrylate) having specific properties

A flame retardant composition for flammable plastic materials and a method for producing the same are disclosed. The flame retardant composition comprises 2,4,6-tris(2,4,6-tribromophenoxy)-1,3,5-triazine that contains 1 to 1000 ppm of a metal species of a water-insoluble polyvalent metal compound selected from the group consisting of oxide, hydroxide, carbonate, phosphate, sulfate and silicate present in the particles of 2,4,6-tris(2,4,6-tribromophenoxy)-1,3,5-triazine. The flame retardant composition is produced by reacting an alkali metal salt of 2,4,6-tribromophenol and cyanuric chloride in the presence of said water-insoluble polyvalent metal compound.
