。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.
