Question

mechanism of cationic, anionic and free radical addition polymerization

Answer 1

Cationic polymerization is a type of chain growth polymerization in which a cationic initiator transfers charge to a monomer which then becomes reactive. ... Similar to anionic polymerization reactions, cationic polymerization reactions are very sensitive to the type of solvent used.
Free-radical polymerization (FRP) is a method of polymerization by which a polymer forms by the successive addition of free-radicalbuilding blocks. Free radicals can be formed by a number of different mechanisms, usually involving separate initiator molecules.
