。Application
1. Polymerization of styrene
LQ-TBEC can be used for the polymerization and copolymerization of styrene in the temperature range of 100-130℃. in a mass process, LQ-TBEC can be advantageously used to increase polymerization rates.
2. Polymerization of acrylates and methacrylates
LQ-TBEC can be used as initiator for the solution (co)polymerization of acrylates and methcrylates in the temperatures range of 100-170℃, amongst others for the coatings.
LQ-TBEC can also be applied as an initiator for the bulk and suspension (co)polymerization of acrylates and methcrylates.
3. Peroxides for Thermoset Resins
LQ-TBEC, tert-butylperoxy 2-ethylhexyl carbonate, is an aliphatic perester that is used for the curing of unsaturated polyester resins at elevated temperatures.
