Thermal polymerization
Microwave and high-frequency polymerization

The activation of the chemical process is due to a number of phenomena: the presence of ionic or radical catalysts, the presence of free radicals obtained from the monomers, the absorption of high-energy photons or, finally, the rise in temperature due to the existence of a hot source, which can result from the exothermicity of chemical reactions between the monomers. The term polymerization has its full meaning in the [ ], ref. concerning the principles of polymerization under high photon...
