    • A process of evaporating a viscous polymer solution is described. The process includes: (a) providing a viscous polymer solution including at least 30 wt. % of solvents and monomers; (b) introducing the viscous polymer solution into a heated helix (5), the heated helix having a vapor exit velocity of 200 to 300 m/s, (a film flow including a two-phase mixture of polymer melt, and solvent vapors and monomer vapors being formed within the helix); (c) forwarding the film flow from helix (5) into a heated vapor separator (6); (d) expanding the two-phase mixture of polymer melt, and solvent vapors and monomer vapors of the film flow within vapor separator (6) at an absolute pressure of 10 mbar to 800 mbar, (a bottom product including a concentrated melt of the polymer is formed within the vapor separator); and (e) withdrawing the bottom product from vapor separator (6). Each of the helix (5) and vapor separator (6) have a separate heating device, and each of heating device independently provides a temperature that is above the softening point of the polymer.

    • An apparatus for degassing plastic materials, e.g., high molecular weight polycarbonate solutions, is described. The apparatus includes a double-shaft extruder having a length-to-diameter ratio of less than or equal to 40, which comprises: (i) two co-rotating and meshing shafts; (ii) an intake opening; and (iii) upstream and downstream portions relative to the intake opening. The shafts of the extruder are designed with a double lead in a degassing zone, and with a triple lead in a pressure build-up zone. Each of the degassing and the pressure build-up zones are down-stream from the intake opening, and the pressure build-up zone is further down-stream than the degassing zone. Also described is a process for degassing plastic materials, which involves providing the described double-shaft co-rotating extruder, into which plastic material is fed, processed and degassed. Entraining agents, such as nitrogen, and other processing additives may be introduced into an extruder during the process of the present invention.
    • 描述了用于对塑料材料(例如高分子量聚碳酸酯溶液)进行脱气的设备。 该设备包括长径比小于或等于40的双轴挤出机,其包括:(i)两个共同旋转和啮合的轴; (ii)进气口; 和(iii)相对于进气口的上游和下游部分。 挤出机的轴设计为具有脱气区域中的双引线,并且在压力增加区域中具有三重引线。 每个脱气和压力积聚区域从进气口向下游,并且压力积聚区域比脱气区域进一步下游。 还描述了一种用于对塑料材料进行脱气的方法,其涉及提供所描述的双轴同向旋转挤出机,塑料进料,加工和脱气。 在本发明的方法中,可将引入剂如氮气和其它加工添加剂引入挤出机中。
