。Application

1.Polymerization of styrene

　LQ-DCP can be used for the polymerization and (co)polymerization of styrene in the 

　temperature range of 110-165℃. polymerization of styrene in a mass process, LQ-DCP can be 

　obtained at increased polymerization rate.

2.Coagent in flame-retardant polystyrene

　LQ-DCP may also be used as synergistic co-agent in combination with halogen containing flame

　retardants to produce flame-retardant expandable polystyrene.

3.Rubber crosslink

　Rubber compounds containing LQ-DCP have good processing safety with a moderate rate of cure.
