For the first time, a quantum-chemical study of the mechanism of initiation of the cationic polymerization monomer of p-methylstyrene in the presence of a complex catalyst of aluminum chloride - hydrochloric acid in toluene with a stoichiometric composition of 1:1:1 by the ab initio method with the reaction coordinate RC1-H20 was performed. The reaction is exothermic . The activation energy of the reaction is 14 kJ/mol, and the thermal effect is -110 kJ/mol.

The ab initio 3.21G method was used to study the initiation mechanism of 2-methylpentene-1 under the action of a complex catalyst AlClCH - HO in heptane of stoichiometric composition 1:1:1:1. The energetics of this reaction is estimated, the values of its energy barrier and enthalpy are obtained.

Based on cluster model, we have calculated the fundamental vibrational frequencies of rutile by combining ab initio method and Wilson’s GF-matrix method. In the calculation, we have introduced the concept of environment factor α to correct the force field of the cluster model. The results of calculation are in good agreement to the experimental data and the normal modes give us clear physical picture of the crystal vibration.
