摘　　要：研究了1种新型富芳香结构的含磷聚合物阻燃剂聚苯基磷酸(9,10-二氢-9-氧杂-10-膦酰杂菲)苯撑酯(PDPPP)的合成及其对环氧树脂(ER)、不饱和聚酯树脂(USPE)的阻燃性能的影响。这种阻燃剂是由2-(6-氧-6氢-膦酰杂菲)1,4-对苯二酚(ODOPB)与苯膦酰二氯通过熔融缩聚获得。将磷含量为13.8%的PDPPP添加到环氧树脂、不饱和树脂中,结果表明该聚合物对环氧树脂、不饱和树脂具有良好的阻燃性能,PDPPP含量只需达到2%即磷含量只需达到0.28%时氧指数LOI可达28,阻燃性UL-94可达到V0级。A novel phosphorus-containing polymeric flame retardant, PDPPP, was synthesized from phenylphosphonic dichloride（PPD） and 2 - （6 - oxido - 6H - dibenz 〈 c, e 〉 〈 1, 2 〉 oxaphosphorin - 6 - yl） 1, 4-benzenediol （ODOPB）. The flame- retardant in which phosphorus content was 1 .8 , was bonded both in the main chains and in the pendant chains of the polymer molecules showed that the PDPPP with high phosphorus content and rich aryl group structures contributed an excellent flame retardancy to epoxy resin and unsaturated polyester. When the PDPPP content in epoxy resin or unsaturated polyester was only 2 percent, eg phosphous content was 0.28 percent, the LOI rached 28 and the UL- 94 rached VO grade.
