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.

摘要： Increasing the endcap level to a level greater than about 90% for Optical Quality (OQ) Melt Polycarbonate significantly reduces the as-molded static charge for injection molded parts for Optical Disc applications. The use of resins with higher endcap levels in combination with antistatic additives provides a highly robust formulation suitable for even the most demanding emerging formats as Digital Versatile Disc (DVD) and in all commercial Optical media molding machines. Thus, optical quality polycarbonates are prepared by performing a base-catalyzed polymerization of a diaryl carbonate and a dihydric phenol under conditions effective to produce a polycarbonate product having an endcap level of 90% or greater.
