Abstract

This invention provides a method for preparing polycarbonates, which utilizes polycondensation catalysta of the formula Ax+MF6-x, wherein A is an alkali metal or alkaline earth cation; M is a transition metal of group IVA or VA, or M is a p-block metal of group IIIB, IVB or VB; and x is 1, 2, or 3. We have found that this new class of catalysts provide excellent polmerization rates for hte prepartion of Bisphenol A polycarbonate form teh metl polmerization rates for the preparation of Bisphenol A polycarbonate form the melt polymerization of disphenyl carbonate and Bisphenol A. Moreover, the catalysts of the invention were found to be very selective in substantially reducingt the level of branching side reation, i.e., formation of Fries product, normally assocatiated with the melt polycarbonate process.
