摘要： 以丙烯酸松香与液溴加成,合成了溴化丙烯酸松香;研究了反应温度、原料的物质的量比、反应时间等因素对反应过程及产物性能的影响。用FT-IR、1HNMR和热重分析(TG)等对溴化丙烯酸松香进行了表征。结果表明,当反应温度为-2～4℃、反应时间5～6h、液溴与丙烯酸松香的物质的量比值约为1.2时,收率可达93%。溴化丙烯酸松香不仅具有较好的阻燃性,同时还拓宽了松香的应用范围,提高了其附加值。

Abstract: Bromination of acrylic rosin with bromine was carried out. The influences of reaction parameters were discussed respectively, such as reaction temperature, mole ratio of material, reaction time etc.. FT-IR,1HNMR and TG of the brominated acrylic rosin were discussed. The result showed that, reaction temperature -2-4℃, reaction time 5-6h and mole ratio of material 1.2:1(Br:rosin), the product yield could be up to 93%. Brominated acrylic rosin had not only better fire-retardant property, but also widened the application of rosin and increased its worth.

Key words: brominating acrylic rosin, acrylic rosin, flame retardation, TG
