Application

Initiator for the (co)polymerization of styrene, ethylene, vinyl chloride, vinylidene chloride, acrylates and methacrylates.

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.
Conversion/time and conversion rate/time curves are given in Figure 1. These experiments were carried out in a 5-liter reactor, using 0.10% (on VCM) polyvinylalcohol (Alcotex® B72), as a protective colloid.
Conversion and conversion rate are determined by means of gaschromatography applying tracer quantities of n-butane (method available on request).

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).
