Cationic polymerization

Cationic polymerization is a type of chain growth polymerization in which a cationic initiator transfers charge to a monomer which then becomes reactive. This reactive monomer goes on to react similarly with other monomers to form a polymer. The types of monomers necessary for cationic polymerization are limited to olefins with electron-donating substituents and heterocycles.

Polymer Synthesis

High monomer purity is also very important in order to obtain high-molecular-weight polymer. In A~A/B~B polycondensation, the incorporation of any monomer that is mono-functional (i.e., having a single A or B group) in the growing polymer chain will terminate † It follows that the number-average molecular weight is given as M n = M o p
