    Polymerization of vinyl chloride: Laurox is a widely used initiator for the suspension and mass polymerization of vinyl chloride between 60°C and 80°C. In many cases Laurox is combined with a more active initiator, such as a peroxydicarbonate (e.g. Perkadox 16) to increase reactor efficiency. Polymerization of ethylene: Laurox is used as an initiator for the high pressure polymerization of ethylene, but because of its poor solubility in most aliphatics, it is in many cases replaced by other peroxides such as Di(3,5,5-trimethylhexanoyl) peroxide (Trigonox 36). The advantage of Laurox is the possibility of storing at ambient temperature. Polymerization of acrylates and methacrylates: Laurox is also used as an initiator for the polymerization of methylmethacrylate at 60-90°C. Laurox is often applied as a replacement for 2,2'-Azobis(isobutyronitril) (Perkadox AIBN).
