摘要： The invention relates to a method for increasing the molecular weight of a polymer granulate from a polycondenstion system. Said polymer granulate is at least partially crystallised and is brought into direct contact with nitrogen-containing treatment gas which is guided in a circuit in a post condensation stage . The temperature of the polymer granulate in the post condensation stage is increased to between 175 250 °C with respect to the granulate from the polymer condensation system. A nitrogen rich unburnt gas which is obtained from air by means of physical methods and which has a residual oxygen content of between 0.1 5 vol. % and which also contains hydrocarbons is added to the treatment gas before it is directed via an oxidation stage and subsequently, to the post condensation stage.

摘要： The invention relates to small pieces of carpet which are introduced into a first impeller type mixer together with an aqueous solution containing a separating salt in order to obtain a first suspension which is guided to a first mechanical separating step. A high-solid phase is extracted therefrom, as is a second high-solid phase which contains a polymer fibre material, and a liquid phase. The second high-solid phase is mixed with a separating solution containing water in an impeller type mixer and a second suspension is produced which is guided to a second mechanical separating step. A third high-solid phase is extracted therefrom, along with a phase rich in polymer fibre material and a liquid phase. An acid is introduced into the impeller-type mixer along with the separating solution containing water, said acid being stronger than H2 CO3, and the pH value of the liquid phase in the impeller type mixer is adjusted to 2-6.

摘要： According to a method for producing polyesters, the esterification of dicarboxylic acids and diols ensues in at least one reaction stage, the pre-polycondensation of the esterification product ensues in at least one reaction stage, and the polycondensation of the pre-polycondensation product ensues in at least one reaction stage. In order to increase the capacity of a system composed of one or more reaction stages and provided for producing polyesters, the supplied product flow, in at least one of the reaction stages, is split into at least two partial flows before or inside the reaction stage, and the partial flows are guided through the reaction stage while being entirely or partially separated from one another.

摘要： Es wird ein Verfahren zur Herstellung von stabilisiertem Polyamid 6 beschrieben, bei dem man die Amino-Endgruppen von getrocknetem und entmonomerisiertem Polyamid 6 in schmelzflüssiger Phase durch Umsetzung mit einem Lacton oder einem Säureanhydrid blockiert. Das so erhaltene stabilisierte Polyamid 6 weist einen Gesamtgehalt an Oligomeren und Monomeren unter 1 Gewichtsprozent auf.
