英文摘要：

An overview of recent years research development on phosphorus-based flame retardant systems used for PBT was presented. The kinds and characteristics of inorganic and organic phosphorus-based flame retardant systems,and their effects on flame retardancy were reviewed in detail. The flame retardant mechanisms of these systems were briefly introduced,and their advantages and disadvantages were also evaluated. Finally,the development and application trends of phosphorus-based flame retardant systems for PBT were presented.
