Ionic vs. free radical polymerization
Web28 feb. 2015 · The mechanism of the new Radical Ring-opening Redox Polymerization (R3P) of 3,6-dioxa-1,8-octanedithiol (DODT) by triethylamine (TEA) and dilute H2O2 was investigated. Scouting studies showed that the formation of high molecular weight polymers required a 1:2 molar ratio of DODT to TEA and of DODT to H2O2. Further investigation … WebIndeed, free radical polymerization of simple substituted alkenes is so facile that bulk quantities of these compounds must be protected by small amounts of radical inhibitors during storage. These inhibitors, or radical scavengers, may themselves be radicals (e.g. oxygen and galvinoxyl ) or compounds that react rapidly with propagating radicals to …
