ACIDIC FORCE OF PROTON DONORS IN COMPLEXE S OF NON-TRANSITION METALS HALOGENIDES AS THE MEASURE OF ACTIVITY OF ELECTROPHILIC POLYMERIZATIONCATALYSTS

The data on the estimation of acidic force of complexes which are form ers under interactions of Lewis acids and proton donors as well as the relation of acidic force to the activity and selectivity of the effec t of a foreside complex compounds as catalysts of electrophilic proces s arc generalised. Aluminium and magnesium chlorides, and boron fluori de-based complexes are considered. It is shown that the increase of ac idic force as the catalyst of electrophilic reactions of polymerisatio n follows by the increase their activity, but reduces the selectivity of the process.
