Abstract: Abstract Free radical polymerization provides a good example of a process for which nonlinear kinetics of a complex system is governed to a great extent by the physical properties of the medium. The kinetic scheme of bulk and solution polymerizations includes the following reactions: Initiation: $$I\xrightarrow{{{{k}_{J}}}}2{{R}^{*}}$$ $${{R}^{*}} + M\xrightarrow{{{{k}_{{pi}}}}}{{R}_{1}}$$ Propagation: $${{R}_{n}} + M\xrightarrow{{{{k}_{p}}}}{{R}_{{n + 1}}}$$ Chain transfer: $${{R}_{n}} + T\xrightarrow{{{{k}_{{lr}}}}}{{P}_{n}} + {{R}_{1}}$$ Termination (a) by combination: $${{R}_{n}} + {{R}_{m}}\xrightarrow{{\left( {1 - \lambda } \right){{k}_{1}}}}{{P}_{{n + m}}}$$ (b) by disproportionation: $${{R}_{n}} + {{R}_{m}}\xrightarrow{{\lambda {{k}_{1}}}}{{P}_{n}} + {{P}_{m}}$$
