    • The process for preparing a polyamide based on dicarboxylic acids and diamines has the following stages: 1) providing an aqueous monomer mixture of dicarboxylic acids and diamines, the molar ratio of dicarboxylic acids to diamines being adjusted such that a molar deficiency of dicarboxylic acids or diamines of from 1 to 10 mol % is present at the outlet of stage 3), based on the other component in each case, 2) transferring the aqueous mixture from stage 1) to a continuous evaporator reactor in which diamines and dicarboxylic acids are reacted at a temperature in the range from 100 to 370° C. and a pressure in the range from 1 to 50 bar, 3) transferring the mixture from stage 2) to a separator which is operated at a temperature in the range from 100 to 370° C. with removal of gaseous components, 4) transferring the mixture from stage 3) together with diamine or dicarboxylic acid in an amount suitable to balance out the molar deficiency into an extruder which is operated at a temperature in the range from 150 to 400° C. for a residence time in the range from 10 seconds to 30 minutes to remove gaseous components through devolatilizing orifices.
    • 制备基于二羧酸和二胺的聚酰胺的方法具有以下阶段:1)提供二羧酸和二胺的单体混合物,二羧酸与二胺的摩尔比被调整为使二羧酸或二胺的摩尔量不足 在阶段3)的出口处存在1至10摩尔%,基于每种情况下的其它组分,2)将水性混合物从阶段1)转移到连续的蒸发器反应器中,其中二胺和二羧酸在 温度范围为100至370℃,压力范围为1至50巴,3)将混合物从阶段2转移至分离器,该分离器的运行温度范围为100至370℃ C.去除气体组分,4)将来自级3)的混合物与二胺或二羧酸一起转移,其量适合于将摩尔不足量平衡到在温度下操作的挤出机 在150至400℃的范围内,停留时间在10秒至30分钟的范围内,以通过脱挥发泡孔除去气体组分。

    • Process for preparation of impact-resistant polystyrene from diene monomers and from styrene monomers via anionic polymerization, where 1) in a stage 1) a rubber solution is prepared from the diene monomers, or from the diene monomers and from the styrene monomers, using an alkali metal organyl compound as initiator and with concomitant use of a solvent, and then 2) in a stage 2), styrene monomer is added to the rubber solution, and the resultant mixture is polymerized anionically to give the impact-resistant polystyrene,  and where, after stage 1) and prior to stage 2), an organylaluminum compound and an alkali metal hydride are added to the rubber solution.
