Notes:
The cationic polymerization of 1,3-pentadiene initiated with aluminium chloride was studied in a non-polar solvent. Experiments carried out in the presence of 2,6-di-tert-butylpyridine (DtBP) clearly demonstrated that the major initiation process is the direct initiation mechanism, even though the existence of a cocatalytic mechanism to small extent cannot be rejected. This result is also evidenced by the linear dependence of the conversion on AlCl3 concentration, and by experiments carried out in the presence of hydrogen chloride showing the independence of the polymerization yield on the hydrogen chloride concentration.
