摘　　要：以马来松香和液溴为原料,合成了溴化马来松香;再与环氧氯丙烷发生酯化反应、闭环反应,合成了溴化马来松香环氧树脂。结果表明,在适宜的条件下,合成的环氧树脂的环氧值为0.30 mol.(100 g)-1。用红外光谱(FT-IR)、核磁共振谱(1H NMR)和元素分析法对产物进行了表征。采用固化剂4,4′-二氨基二苯甲烷(DDM)对产物进行了固化。实验证明,溴化马来松香环氧树脂固化物具有较好的阻燃性。Brominated maleic rosin was produced from maleic rosin and bromine, and then brominated maleic rosin epoxy resin was synthesized by ring-open and ring-closing reaction from brominated maleic rosin and epichlorohydrin. Epoxy value of the epoxy resin, which was prepared under suitable conditions, was 0.30 mol · （100 g）^-l. The product was characterized by FT-IR,^1 H NMR and bromine element analysis. Brominated maleic rosin epoxy resin was cured by diaminodiphenylmethane （DDM）. The experiment proved better flame retardation of the curing product of brominated maleic rosin epoxy resin and DDM.
