Abstract

Stable organic cations have provided a range of initiator systems for a wide variety of cationic polymerisations of olefinic and hetercyclic monomers. Such salts are readily characterised in purified form, and facilitate experimental work leading to determination of ion-pair dissociation equilibria and estimates of rate coefficients for propagation by free cations and well defined ion pairs. Data obtained in this way permit (and stimulate) comparison with polymerisations initiated by more complex systems and afford opportunities for quantitative study of counterion phenemona on the various processes governing molecular weights and molecular weight distributions.
