Cyclic monomers such as cyclohexene oxide were readily polymerized upon irradiation of the CT complexes of pyridinium salts whereas spontaneous polymerizations were observed upon mixing with strong electron donating monomers such as butyl vinylether and A-vinyl carbazole. These monomers are known to form CT complexes themselves with electron acceptors which may interfere with the rapid polymerization observed.

Thus there are many examples of PEG acting as a PTC (refer also to other contributions to the Symposium). It is of interest to inquire as to the effectiveness of other polyethers. Yamazaki and coworkers have examined the effect of various polymeric additives on the reaction between sodium phenoxide and n-butyl bromide in dioxane. Poly(oxetane), poly(tetrahydrofuran), and poly(ethyl-vinylether) were found to be ineffective, while PEG gave a rate enhancement of approximately 100. Interestingly, polyvinylpyrrolidone of several molecular weights was even more effective than PEG. ...
