There is growing interest in various “Living Free Radical Polymer synthesis” techniques (in which supply of reagents can be used to control the extent or rate of the reaction), as these techniques give far more control over the size (and topology) of the molecules formed.
There are various Living Polymer synthesis techniques, including
• Reversible Addition Fragmentation Chain Transfer (RAFT)
• Atom transfer radical polymer synthesis(ATRP)
• Nitroxide-mediated polymer synthesis (NMP)
Continuous processing offers a way to carry out these processes with great repeatability and control. With inline degassing and long residence time stainless steel reactors, processes that are very oxygen sensitive can be carried out.
