The Difference Between Cationic and Anionic Polymerization

Cationic and anionic polymerization are two different methods used to produce polymers, which are large molecules composed of repeating structural units. Cationic polymerization involves the addition of a cationic initiator to a monomer, which causes the monomer to covalently bond with the initiator. Anionic polymerization involves the addition of an anionic initiator to a monomer, which causes the monomer to covalently bond with the initiator (Gong et al., 2020). Cationic polymerization typically proceeds at a faster rate than anionic polymerization. This is due to the nature of the cationic initiator, which has a positive charge and is more easily attracted to the electron-rich monomer. The positive charge of the initiator helps to facilitate the reaction and allows it to occur more quickly (Gong et al., 2020). Furthermore, the cationic initiator can also act as a catalyst, further speeding up the reaction. Anionic polymerization often requires higher temperatures than cationic polymerization, as the anionic initiator has a negative charge, causing it to interact less strongly with the. Cont…
