Kinetics of Free Radical Polymerization
" Chain-growth polymerization or addition polymerization reaction is a polymerization technique where unsaturated monomer (means containing double and triple bonds in their molecular formula) molecules add onto the active site on a growing polymer chain one at a time ". Since, we know that d epending on this active site present on the growing polymer chain, there are three types of addition polymerization: free radical polymerization, ionic polymerization, and coordination polymerization. Free radical polymerization is one of those types of additional polymerization in which the active site is free radical. In this, initiators are used to generate free radicals. Free radical is denoted as "M•". ➛ Initiator molecules are of the following types; (a) Thermal initiators (such as peroxides, azo-compounds) (b) Photochemical initiators (such as Disulfides, ketones, Azo, Peroxides,etc.) (c) Redox initiators (such as Fenton reagent) (d) Ionising initiators ( su...
