  • Applications

    For Polymer production and Poly(meth)acrylics: Trigonox K-90 may be used for various polymerization reactions. It can be used in emulsion, solution and bulk polymerizations. In emulsion processes, Trigonox K-90 may be activated by organic-soluble or water-soluble reducing agents, or by metal compounds to achieve polymerization at room temperature or lower. When no accelerators are used, effective polymerization can be obtained in the temperature range of 50-200°C. For example, styrene and methyl methacrylate can be polymerized in bulk in the temperature range of 60-100°C using Trigonox K-90. Trigonox K-90 may also be used for emulsion polymerization of various vinyl monomers. In this case Trigonox K-90 may be used in combination with reducing agents to achieve reproducible results at low temperatures. For Thermoset: Trigonox K-90 may be used as an initiator for the room temperature cure of promoted unsaturated polyester and vinyl ester resins, and elevated temperature cure of non-promoted resins.
