Description
Summary:A general mechanism is proposed in this paper with the assumption of homopolymerization, cross‐propagation and kinetically‐controlled termination and a quantitative treatment method is developed. The model proposed is different from that of Shirota and Shan. The kinetic models concerning the participation of charge‐transfer complexed (CTC) monomer and homopolymerization or otherwise, and kinetic‐ or diffusion‐controlled termination are generalized into one equation. The quantitative treatment method proposed can give monomer reactivity ratios without concerning the specific kinetic model. Meanwhile, information on the termination process can also be acquired from the quantitative treatment method. Copyright © 2003 Society of Chemical Industry
