Applications

Polymerization of ethylene

• LQ-CPND-C75 is an efficient initiator for the ethylene polymerization under high pressure in both autoclave and tubular processes. To obtain a wide spectrum of polymerization, temperatures combinations with other peroxides are applied in practice. Depending on reaction conditions, LQ-CPND-C75 is active in the temperature range of 130-170℃.

Polymerization of vinylchloride

• LQ-CPND-C75 is used as an initiator for the suspension and mass polymerization of vinylchloride between 40℃ and 65℃. LQ-CPND-C75 is often combined with less active peroxides such as peroxydicarbonates (e.g. LQ-BCHPC) or diacylperoxides (e.g.LQ-LPO .) to increase reactor efficiency.
