This paper describes the development of a mathematical model for the polymerization of isobutylene initiated with Et 2 AlCl + Cl 2 . Previous experiments have shown that this polymerization is “kinetically living”. A computer analysis based on our mathematical model permits the calculation of the theoretical conversion–time curves, the molecular weight averages, and polydispersity. The good agreement between experimental and theoretical results suggests that the reaction mechanism proposed and the mathematical model derived are quite correct.
