What is the difference between cationic and anionic polymerization?
The main difference between cationic and anionic polymerization is that cationic polymerization is initiated by a cationic species, whereas anionic polymerization is initiated by anionic species. Polymerization is a chemical process in which small molecules called monomers react with each other to form long chains or networks known as polymers.
Can cationic polymers be used outdoors?
Some types of anionic polymers like epoxys cannot be used outdoors due to their poor UV resistance which causes yellowing. Overall, cationic polymers tend to be more versatile for acrylics than anionic polymers due to their positive charge and properties.
Why are cationic polymers not widely used?
In this reaction, a cation (an ion with a positive charge) transfers its charge to a monomer to form the positively-charged polymer, which consequently grows by reacting with other monomers. Cationic polymers are not used as widespread, because there are only a few polymers that can successfully execute cationic polymerization.
What is cationic polymerization?
Cationic polymerization is a chain growth polymerization mechanism where the polymerization is initiated through the formation of a carbocation intermediate. This carbocation serves as the active center for polymerization. Subsequently, monomer molecules react with carbocation, resulting in the propagation of the polymer chain.
