Dibromoneopentyl glycol

Another approach to durable press—flame retardancy uses a combination of a cross-linking system, antimony(III) oxide, and a bromine-containing reactive additive, namely dibromoneopentyl glycol, to achieve dual properties (120,121). [Pg.490]

Halogenated intermediates, dibromoneopentyl glycol [3296-90-0] (DBNPG), and alkoxylated derivatives of tetrabromobisphenol A are used extensively in flame-retardant apphcations. Similar properties can be derived from halogenated dibasic acids, chlorendic anhydride [115-27-5] (CAN), and tetrabromophthahc anhydride [632-79-1] (TBPA). Processes can be used to produce brominated products by the in situ bromination of polymers derived from tetrahydrophthahc anhydride. [Pg.313]

Flame-Retardant Resins. Flame-retardant resins are formulated to conform to fire safety specifications developed for constmction as well as marine and electrical appHcations. Resins produced from halogenated intermediates (Table 5) are usually processed at lower temperatures (180°C) to prevent excessive discoloration. Dibromoneopentyl glycol [3296-90-0] (DBNPG) also requires glass-lined equipment due to its corrosive nature. Tetrabromophthahc anhydride (TBPA) and chlorendic anhydride (8) are formulated with ethylene glycols to maximize fiame-retardant properties reaction cycle times are about 12 h. Resins are also produced commercially by the in situ bromination of polyester resins derived from tetrahydrophthahc anhydride... [Pg.317]

The main reactive flame-retardant compounds used in unsaturated polyesters are tetrabro-mophthalic anhydride, dibromoneopentyl glycol, bis(2-hydroxyethyl) ether of tetrabromobisphenol A, and chlorendic anhydride. Tetrachlorophthalic anhydride is also used. [Pg.90]

There are two basic types of flame-retardant chemicals reactive FRs and additive FRs. Reactive FRs are usually introduced during the polymerization stage and copolymerized, together with other monomers. They therefore have only minimal effect on mechanical properties. Typical examples are tetrabromobisphenol A, dibromoneopentyl glycol, vinyl chloride, and bromo- or dibromostyrene. [Pg.118]
