Photo-induced cationic polymerizations of styrene and x-methylstyrene, which are weak electron donors and contain no hetero atom, were carried out in the presence of electron acceptors such as tetracyanobenzene and pyromellitic dianhydride to elucidate the polymerization mechanism initiated through an excited charge transfer interaction. Cyclohexene oxide was also polymerized by photo-illuminat...

In this review, we report some recent advances and new horizons in UV-induced cationic photopolymerization. In particular, after a brief introduction on the discovery and affirmation of the cationic photopolymerization process, new efforts in the synthesis of cationic photoinitiators are reported. Subsequently, an interesting and absolutely new application is reported, related to the combinatio...

A clickable initiator, pentafluoro benzyl bromide, has been investigated for the cationic ring opening polymerization of poly(2-oxazolines).

Biobased exo-methylene-conjugated dienes underwent regioselective living cationic polymerization to result in well-defined homo- and copolymers with good thermal properties.

Cationic β-C–H and β-C–C scissions were employed for selective cationic dimerization of α-methylstyrene (αMS) derivatives to synthesize exo-olefin compounds subsequent sulfur-free RAFT polymerization αMS isobutylene (IB) produce polymers with controlled structures, respectively, as reported by Masami Kamigaito et al. in their Research Article (e202307791).
