|  | Stable Free Radical Polymerization
Stable Free Radical Polymerization is a process-oriented technology that facilitates the preparation of linear or branched polymers having narrow molecular weight distributions and reactive end groups on each polymer chain. The process can also produce block co-polymers having unique properties. Process conditions allow high (essentially 100%) conversions at reasonable process temperatures (less than 130 degrees Celsius). The process is especially applicable to acrylates, styrenes, and dienes.
Furthermore nitroxide-based stable free radical polymerization is particularly suited for emulsion or microsuspension polymerization. In addition to the patents listed below, there are a number of patent applications in process plus additional process know-how available for license.
Technology Description |
Stable Free Radical Polymerization is a process-oriented technology that facilitates the preparation of linear or branched polymers having narrow molecular weight distributions and reactive end groups on each polymer chain. The process can also produce block co-polymers having unique properties. Process conditions allow high (essentially 100%) conversions at reasonable process temperatures (around 135 degrees Celsius). The process is especially applicable to acrylates, styrenes, and dienes. Nitroxidebased stable free radical polymerization is particularly suited for emulsion or microsuspension polymerization. In addition to the current patents, there are a number of patent applications and process know-how available for license.
