Synthesis and characterization of a DOPO-substitued organophosphorus oligomer and its application in flame retardant epoxy resins

▶ The organophosphorus oligomer synthesized possesses rich aryl group structures. ▶ The organophosphorus oligomer synthesized has high flame retardant efficiency. ▶ The TG-FTIR and DP-MS analysis provide the insight into flame retardant mechanism.
