Initiator for the (co)polymerization of vinylchloride, vinylidenechloride, acrylates and methacrylates.
* Polymerization of vinylchloride
Laurox W-40 is widely used as an initiator for the suspension polymerization of vinylchloride in the temperature range between 60'C and 80'C.
In many cases Laurox W-40 is combined with a more active initiator such as a peroxydicarbonate (e.g. Perkadox 16) to increase reactor efficiency.
Reasons to use a water-based peroxide suspension instead of a solid or solvent-based peroxide are the following:
- Enhanced safety
- Solvent free. No contamination of the VCM recycle stream
- Enhancement of PVC purity
- Easy to use (pumpable) in "closed reactor technology"
- Easy to dilute with water |
