Styrene is a very important chemical raw material,whether in production,transportation,or storage,it may cause irreversible losses and even safety accidents due to its self polymerization reaction.The issue of styrene polymerization is a thorny issue faced by styrene plants nationwide.Styrene,as a very important chemical raw material,may undergo self polymerization reactions during production,transportation,and storage,resulting in irreversible losses and even safety accidents.The problem of styrene polymerization is a thorny issue faced by styrene plants nationwide.Starting from the polymerization mechanism of styrene,this article analyzes the possible reasons for styrene polymerization,and combines production practice from aspects such as temperature,polymerization inhibitors,fillers,and processes corresponding anti polymerization measures have been proposed to prevent its self polymerization reaction or slow down its polymerization rate,so that styrene can be stored for a longer time,which is of great significance for the industrial production of styrene.
