Using low conversion bulk copolymerization experimental data and the apparent rate constant model, the monomer chain cross‐transfer rate constants and the cross‐termination coefficient were evaluated. It was found that the dependence of the cross‐termination coefficient on composition is a function of initiator efficiency and that monomer chain cross‐transfer rate constant are relevant for the theoretical estimation of the molecular weights and molecular weight distributions.
