| Classes of polymers/Polymerizations offered by Polyorganix |
Polyorganix is specialized in specialty polymers as well as general polymerizations. Conductive and light emitting polymers, water soluble polymers and polymer-Nano composites are our specialty. We use common Free-radical, anionic and emulsion polymerizations, as well as some modern techniques using RAFT and Hyperbranched polymers. We design synthetic polymers, using all different types of organic reactions like: Condensation reactions, Suzuki coupling, Witting reactions – to name a few.
