摘要
研究了新型有机锑阻燃剂─—二溴三本基锑三谈苯酚衍生物的合成方法，并将其应用于聚乙烯材料获得良好的阻燃效果，每100份树脂（质量）添加10份时，氧指数从18.5提高到26．5，且对聚乙烯的弯曲强度和冲击强度无不良影响。
Bromobenzene, magnesium, antimony trichloride, bromine and tribromophenol actingas raw materials, Dibromotriphenylantimony and its derivative with tribromophenol is syn-thesized- This product has the good fireredtarding effect on polyethlene(PE)' The limintingoxygen index (LOI) has increased 8 than unfilled PE by adding lO parts per 1OO parts ofpolyethylene. The mechanical properties come closer to the unfilled PE by bend density andimpact density investigations.
