Abstract

Abstract:

This article reviewed the research progress in flame⁃retardant polybutylene succinate （PBS） and its flame⁃retardant mechanism in recent years. The commonly used flame retardants for PBS resin include phosphorus⁃nitrogen based flame retardants， nano flame retardants， biobased flame retardants， and their compound systems. Among them， phosphorus⁃nitrogen⁃based flame retardants have the most development and modification schemes. Especially， the flame⁃retardant system based on ammonium polyphosphate （APP） currently is the most studied and effective system， including the composite system of APP and nano flame retardants and the composite system of APP and bio⁃based flame retardants. Meanwhile， the article summarized the flame⁃retardant performance and typical flame⁃retardant mechanisms of various flame⁃retardant systems.

Key words: poly（butylene succinate）, flame?retardant modification, research progress
