NEW TECHNOLOGIES: Is Quantum Tunneling Relevant in Free-Radical Polymerization?
Danilo Cuccato, Marco Dossi, Daniela Polino, Carlo Cavallotti, Davide Moscatelli*
Quantum tunneling is investigated on backbiting reactions active in the polymerization of ethylene, styrene, and vinyl chloride. The Eckart model is adopted to estimate tunneling factors and their dependence upon the temperature. The tunneling effect is found to be relevant in particular at the mild conditions typical of the free-radical polymerization of alkenes.
