Initiator for polymerization of vinyl chloride, vinylidine chloride and ethylene.
Polymerization of vinyl chlorideTrigonox 23-W50 has an activity in between peroxydicarbonates and tert-Butyl peroxypivalate (Trigonox 25). Trigonox 23-W50 can be applied as an initiator for the suspension polymerization of vinyl chloride in the temperature range 5065°C. The obtained polymer has a good thermal stability. Conversion/time and conversion rate/time curves are given in Figure 1.
Initiator (50% emulsion in water and methanol) for (co)polymerization of acrylates and methacrylates.
