In the cationic polymerization of trioxane initiated by BF, etheratc in cyclohexane solution, the rate of polymerization may be practically zero after a long period at 56 Β°. If the reaction mixture is then cooled at a controlled rate, it is possible to obtain further increments both in yield and in
## Abstract The kinetics of propylene polymerization catalyzed by a commercial sample of highly activated titanium trichloride and diethylaluminum chloride have been investigated. Polymerizations were carried out at various temperatures, pressures, and catalyst concentrations, and reaction rates we
A~traet A numeric solution is developed for a kinetic scheme involving chain length dependent termination (by disproportionation) and chain transfer on the basis of the harmonic and the geometric mean approximation for the two radicals involved in the termination process. In addition, solutions in t
