Abstract
NEW MATERIAL:The titled diester compound of formula I [R1 and R2 are formula II (X is Br; Y is 1W4C alkyl, 1W4C alkoxy, OH, or primary, secondary or tertiary amine; p is 0W4; q and r are 1W4; q+r≤5].
EXAMPLE: Di-(4-amino-3,5-dibromobenzoic acid)ester.
USE: Fire retardants for various polymeric marerials, esp. thermoplastic materials such as (rubber-modified high impact) polystyrene, ABS resin, polyester, polyamide, polyethylene, polybutadiene, polycarbonate, etc. The agents have little lowering effect to the impact strength and heat deformation temperature of the polymers.
PROCESS: E.g. 3,5,3',5'-tetrabromobisphenol A and a carboxylic acid of formula II (e.g. 4-amino-3,5-dibromobenzoic acid) are esterified in a nonalcoholic solvent in the presence of an acidic catalyst such as phosphorus oxychloride.
