摘要： The invention relates to a method and a device for producing moulded bodies from a highly condensed polyester melt. The invention is characterised in that the melt never solidifies between the polycondensation reactor and the moulding units and that there is no degassing device between the end reactor and said moulding units.

摘要： The invention relates to a method for producing polyesters of aromatic dicarboxylic acids with aliphatic and/or cycloaliphatic diols, during which an aromatic dicarboxylic acid present in a saturated solution is, in the presence of a monocarboxylic acid or of a mixture of a monocarboxylic acid with water or in another suitable solvent, reacted with an aliphatic or cycloaliphatic diol to form a dicarboxylic acid alkane diolester carboxylate and/or oligomers thereof, which can be polycondensed in additional method steps to form polyester.

摘要： The invention relates to a method for producing polyesters or copolyesters without using a balance to dose the solid main raw material dicarboxylic acid, and to a corresponding concept for regulating the molar ratio of the paste prepared from the starting materials, without directly measuring the rate of flow of the solid main raw material dicarboxylic acid by weighing. The invention also relates to an indirect method for determining the raw material consumption without directly weighing the solid raw material. The regulation of the addition rate of the solid raw material is carried out on the basis of the deviation of the density of the finished paste from a solvent.

摘要： Disclosed is a method for producing polyesters by means of esterification or re-esterification, precondensation of the esterified/re-esterified product, and polycondensation of the precondensed product at a pressure of 0.2 to 500 mbar and a temperature of 230 to 330 °C. According to said method, the vapors formed during precondensation and polycondensation are condensed and the obtained cooled diol is redirected into the condensation stage. In order to improve the degree of separation, the vapors are directed into a bottomless direct contact condenser, the base of which is immersed into the top funnel-shaped section of a barometrically dipped downpipe so as to form an annular space, cooled diol is sprayed into the vapors in the top section of the direct contact condenser, the remaining vapors are recovered via the annular space, and the formed polymer aggregates are removed.
