The present invention provides novel pentabromobenzyl alkyl ethers serving as highly effective flame retardants in polymers. The invention further provides a fire retarded polymer composition comprising said pentabromobenzyl alkyl ethers.
2,3,4,5,6-Pentabromobenzyl bromide reacts with primary and secondary alcohols and also with alkali metal alkoxides derived from primary alcohols to form the corresponding pentabromobenzy] ethers in high yields. In the reactions with secondary alkoxides, considerable amounts of bis(2,3,4,5,6-pentabromobenzy]) ether are formed.
