Polymerization is initiated by free radicals. The function of an inhibitor is to tie up these free radicals by reacting with them to form stable compounds. Korea Bio-Gen's polymerization inhibitors form these stable compounds in the presence of oxygen. The free radical reacts with oxygen to form a peroxy-free radical. The inhibitor reacts with this peroxy-free radical to form a free radical complex. The complex then reacts with another peroxy-free radical to form stable compounds.
Korea Bio-Gen offers a series of polymerization inhibitors that are practical storage and in-process inhibitors when used by themselves or in combinations. Inhibitor selection should be based on evaluation in your specific system.
