Applications
| Application | Description |
|---|---|
| Polymerization of Vinyl Chloride | Widely used in water-phase suspension and bulk polymerization reactions, with temperature range between 60-75℃. Often combined with other high-activity peroxides to enhance reactivity. |
| Polymerization of Ethylene | Used in high-pressure polymerization, but often replaced by peroxynonanoates due to solubility issues. Its key advantage is room-temperature storage. |
| Polymerization of Acrylates and Methacrylates | Can be used in acrylate polymerization reactions at 60-90℃, often replacing more toxic initiators like azobisisobutyronitrile. |
| ABS Resin Polymerization Initiator | Important initiator in ABS polymerization, often used in combination with LQ-CH335 for enhanced initiation efficiency. |
