Photoinduced polymerizations of α‐methylstyrene and styrene were carried out in the presence of electron acceptors. These polymerizations are proved to be initiated by radical, ion‐pair, or free ion formed through the photoexcited electron donor‐acceptor complex. Radiation‐induced cationic polymerizations of styrene and α‐methylstyrene were found to proceed by free cationic propagation. The effect of added electron acceptors in these polymerizations was investigated. The role of ion‐pair in radiation‐induced cationic polymerization is investigated by the use of optical absorption method at 77°K and pulse‐radiolysis technique at room temperature.
