Process for producing raw polycarbonate resin material and producing polycarbonate resin

摘要

The invention relates to an inexpensive and simple method for producing a starting material for polycarbonate resin and for producing polycarbonate resin. In the method for producing a starting material for polycarbonate resin production through interfacial polymerization, a molten bisphenol compound is without being solidified, directly mixed with water to be in liquid at a temperature not higher than the melting point of the bisphenol compound, and then dissolved in an aqueous alkali solution.
