    • Disclosed are a method and a device for gradually producing high-molecular polyphosphonates, polysulfones, polyarylates, polyamides, polyarylene ethers, or polyetherketones by melt-condensing a monomer compound carrying hydroxyl groups, carboxyl groups, anhydride groups, phosphoric acid groups, phosphono groups, phosphonate groups, phosphino groups, phosphinate groups, carbonyl groups, sulfonyl groups, sulfonate groups, siloxane groups, or amino groups on its own or along with at least one diphenol, dialcohol, diamine, or a dicarbonate component. According to the invention, a) esterification or reesterification and precondensation are performed in an intermittently operated first reactor (1) in the presence of an esterification catalyst or reesterification catalyst; b) polycondensation is then optionally performed in an intermittently operated intermediate reactor (6) by optionally adding one or several additional monomers, another catalyst, and additives until a predetermined polycondensation level or viscosity level has been attained; and finally c) condensation is continued in an intermittently operated final reactor (12) until the desired polycondensation level or viscosity level has been reached; and d) branching molecules comprising more than two functional groups are optionally added prior to or during esterification or re-esterification, prior to or during polycondensation optionally performed in the intermediate reactor, or prior to or during polycondensation performed in the final reactor. The dwell time in the reactors ranges between 5 minutes and 15 hours while the temperature is set to 180 to 300 °C in reactors (1) and (6) and to 240 to 400 °C in reactor (12), the pressure being continuously or gradually lowered from 2000 to 100 mbar in reactors (1) and (6) and to 100 to 0.01 mbar in reactor (12) by sucking off the vapors produced during condensation.

    • The invention relates to a reactor for the treatment of highly viscous plastic melts, comprising a horizontal, cylindrical container (2) with a vapour exhaust and chambers in the region of the melting bath, formed by the arrangement of panel walls, in which annular discs, fixed to a shaft (3) by spokes and serving as stirrer elements (4, 5) may be rotated, whereby, in the cavities of the annular discs (4, 5), two opposing scrapers (6, 7) are fixed to the inside of the container at an offset angle and run past at a small separation from the front faces of the annular discs and the sleeve of the shaft (3). According to the invention, the assembly and disassembly of the shaft and scraper is simplified by connection of the scraper to the inside of the container by means of a positive connection (13, 19).
    • 用于处理高粘度塑料熔体的反应器本发明涉及一种用于处理高粘度塑料熔体的反应器,该反应器包括具有蒸汽排出装置的水平圆柱形容器(2)和在熔池区域中由腔壁布置形成的腔室,其中环形圆盘 ,通过辐条固定在轴(3)上并作为搅拌器元件(4,5)可以旋转,由此在环形盘(4,5)的空腔中,两个相对的刮板(6,7)固定到 容器的内侧成偏斜角并且从环形盘的前表面和轴(3)的套筒以小间距行进。 根据本发明,通过利用形状连接(13,19)将刮具连接到容器的内部来简化轴和刮板的组装和拆卸。
