Initiator (50% water-based emulsion) for (co)polymerization of vinyl chloride and vinylidine chloride. CAS number: 51240-95-0 EINECS/ELINCS No: 257-077-0 Applications: Polymerization of vinyl chloride: Trigonox 423-W50 is a highly active initiator for the suspension polymerization of vinylchloride in the temperature range between 40°C and 65°C. Trigonox 423-W50 is often combined with less reactive initiators, such as peroxydicarbonates (e.g. Perkadox 16) or diacylperoxides (e.g. Laurox) to increase reactor efficiency. Reasons to use a water-based peroxide emulsion instead of a solvent-based peroxide are the following: enhanced safety, easy to use (pumpable) in ‘closed reactor technology’, easy to dilute with water Information provided by Nouryon |
