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 of brominated maleic rosin and epichlorohydrin. The influence of reaction conditions was discussed
such as ring-open reaction temperature
mole ratio of material
concentration of NaOH and so on. The product which was prepared under suitable conditions had following property: epoxy value 0.30 mol/(100g) -1.The product was characterized by FT-IR and 1H-NMR. Brominated maleic rosin epoxy resin was cured by DDM. The test has proved that the curing product of brominated maleic rosin epoxy resin has better flame retardation.
