Polymerization of ethylene
- LQ-K 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-K is active in the temperature range of 150-190℃.
Polymerization of vinylchloride
- LQ-K is used as an initiator for the suspension and mass polymerization of vinylchloride between 50℃ and 70℃.
