摘　　要：以丙烯酸松香和液溴为原料,合成了溴化丙烯酸松香;再与环氧氯丙烷进行酯化反应、闭环反应,合成了溴化丙烯酸松香环氧树脂。采用固化剂4,4′-二氨基二苯砜(DDS)对产物进行了固化。用红外光谱(FT-IR)、核磁共振谱(1H-NMR)等对产物进行了表征。在适宜的条件下,合成的环氧树脂的环氧值为0.26mol/100g。燃烧实验、热失重和阻燃性实验证明,溴化丙烯酸松香环氧树脂/DDS固化物具有较好的阻燃性。Brominating acrylic rosin was produced from acrylic rosin and bromine, and brominating acrylic rosin epoxy resin was synthesized from brominating acrylic rosin and epichlorohydrin by two-step process. Epoxy value of the product, which was synthesized under suitable conditions, was 0.26 mol/100 g. The chemical structure of brominating acrylic rosin epoxy resin was confirmed by ^1H-NMR spectroscopy and IR spectroscopy. The epoxy resin was cured by DDS. The curing system of DDS and brominating acrylic rosin epoxy resin has better flame retardation.
