摘　　要：本文利用新型无卤反应型阻燃剂中间体9，10-二氢-9-氧杂-10-磷杂菲-10-氧化物（DOPO）与马来酸反应，制备了反应型阻燃剂DOPOMA。并利用其作为反应型阻燃剂与马来酸酐、苯酐、1，2-丙二醇反应，制备通用型透明不饱和聚酯树脂。对合成的通用型不饱和聚酯树脂燃烧行为、热稳定性及固化行为进行研究。结果表明，随磷含量的增加，极限氧指数（LOI）在一定程度上增加。磷系阻燃剂DOPOMA的存在对不饱和聚酯树脂的固化有延迟效应，使得固化引发时间延长。In this paper, new type of reactive flame retardant intermediate 9, 10-dihydro-9-oxa-10- miseellaneou8 Philippine phosphorus-10-oxide （DOPO for short） and maleie acid, were prepared reactive flame retardants DOPOMA, which was used as reactive flame retardants, synthesis with maleic anhydride, phthalic anhydride, 1, 2-propanediol response to prepare transparent general-purpose unsaturated polyester, the fire behavior, thermal stability and curing behavior of unsaturated polyether was studied. The results show that, with the phosphorus content increases, limiting oxygen index （LOI） increase, the existence of DOPOMA has delayed effects on the curing of unsaturated polyether, making the cure time extended.
