Chain initiation and chain propagation steps are involved in a) Cationic polymerization b) Anionic polymerization Free radical polymerization d) Condensation polymerization The correct answer is

Polymerization involves various mechanisms depending upon the initiator. If initiator generates free radical, addition polymerization takes place through free radical mechanisms. If H^(+) is initiator and electron releasing group is present, cationic polymerization takes place. IF electron withdrawing group is present and KNH_(3) is initiator, anionic polymerization takes place. Which of the following will induce anionic polymerization
