It can be considered as an alternative to radical polymerization, and may refer to anionic polymerization or cationic polymerization. As with radical polymerization, reactions are initiated by a reactive … Meer weergeven The potential utility of ionic polymerization was first recorded by Michael Szwarc after a conversation with Samuel Weissman. He and a team, composed of Moshe Levy and Ralph Milkovich, attempted to recreate an … Meer weergeven Because of the polarity of the active group on each polymerizing radical, termination by chain combination is not seen in ionic polymerization. Furthermore, because charge propagation can only occur by covalent bond formation with the compatible … Meer weergeven
