Abstract
A manufacturing method for transparent polyester/polycarbonate compositions using equipment for manufacturing polycarbonates or polyesters by the melt polymerization method comprises a manufacturing method wherein polyester or polycarbonate resin is added to a polymerization vessel or to the outlet side of a polymerization vessel of polycarbonate or polyester manufacturing equipment, or a manufacturing method. The polyester or polycarbonate resin is added to a polymerization vessel in which the polymerization reaction is substantially complete, or to the outlet side of a polymerization vessel, or to the pelletization apparatus of the manufacturing equipment for polycarbonates or polyesters and provides high productivity for manufacturing transparent polyester/polycarbonate compositions with superior impact strength as well as solvent resistance.
