    摘要: A novel flame-retardant material is prepared by copolymerizing pentabromobenzyl-acrylate with a metal salt of a compound of Formula I:
    wherein R₁ is H or lower alkyl, and R₂ is selected from H, lower alkyl and

    OH.
    The novel flame retardant has improved thermal stability and is useful in a variety of uses, e.g. as a flame retardant in engineering plastics and styrenic.
