摘要： A process for preparing an end-capped polycarbonate comprises melt reacting an aromatic dihydroxy compound, a carbonic acid diester, and optionally a catalyst in a prepolymerization vessel to form a polycarbonate product; transferring the polycarbonate product from the prepolymerization vessel; mixing the polycarbonate product with an end-capping agent under hermetic seal at a pressure of at least about 760 mm Hg; and transferring the polycarbonate product and end-capping agent mixture to a postpolymerization vessel to endcap the polycarbonate product. An apparatus for preparing an end-capped polycarbonate comprises a prepolymerization vessel having and inlet and an outlet; a postpolymerization vessel having an inlet and an outlet; a mixer in fluid communication with the outlet of the prepolymerization vessel and the inlet of the postpolymerization vessel; and a charging port through which an end-capping agent is charged to the mixer, wherein the mixer is hermetically sealed at greater than or equal to 760 mm Hg.

摘要： A method of recycling fusible polycondensation resin waste in a fusion polymerization apparatus is disclosed. The method of recycling polycondensation resins comprises adding polycondensation resin waste directly to a fusion polymerization apparatus to carry out the polycondensation reaction. The polycondensation resin waste may be supplied from any point of the polycondensation apparatus to carry out the exchange reaction and/or the polycondensation reaction between the resin being prepared in the apparatus and the resin waste supplied. The method may be carried out in a continuous fusion polycondensation system with more than one polymerization reactor connected in series. The polycondensation resin waste may be supplied from the outlet of a polymerization reactor during the initial stage of the polycondensation process (oligomerisation process) to carry out the exchange reaction and/or the polycondensation reaction between the resin waste and the resin being prepared in the later stage of the polycondensation process in a continuous fusion polycondensation apparatus with more than one polymerization reactor connected in series.
