    • A process for preparing a polyamide by reacting at least one aminonitrile with water comprises: (1) reacting at least one aminonitrile with water at a temperature from 100 to 360° C. and a pressure from 0.1 to 35×106 Pa to obtain a reaction mixture, (2) further reacting the reaction mixture at a temperature from 150 to 400° C. and a pressure which is lower than the pressure in step 1, the temperature and the pressure being selected so as to obtain a first gas phase and a first liquid or a first solid phase or a mixture of first solid and first liquid phase, and the first gas phase is separated from the first liquid or the first solid phase or from the mixture of first liquid and first solid phase, and (3) admixing the first liquid or the first solid phase or the mixture of first liquid and first solid phase with a gaseous or liquid phase comprising water at a temperature from 150 to 360° C. and a pressure from 0.1 to 30×106 Pa to obtain a product mixture.
    • 通过使至少一种氨基腈与水反应制备聚酰胺的方法包括:(1)在100至360℃的温度和0.1至35×10 6 Pa的压力下使至少一种氨基腈与水反应,得到反应混合物, (2)在150-400℃的温度和低于步骤1中的压力的​​压力下使反应混合物进一步反应,选择温度和压力以获得第一气相和第一液体 或第一固相或第一固相和第一液相的混合物,并且第一气相与第一液体或第一固相或第一液体和第一固相的混合物分离,以及(3)将 第一液体或第一固相或第一液体和第一固相的混合物与气相或液相在150至360℃的温度和0.1至30×10 6 Pa的压力下包含水以获得产物混合物。

    • A method for printing a substrate web in a rotary printing press is disclosed. The substrate web to be printed is conveyed through a printing form-based printing unit for static printing of the substrate web with a print image that does not vary for the print copies of a printing job, such that at least one static print page is printed in the longitudinal direction of the substrate web per revolution of the form cylinder and several static print pages are printed on the substrate web across the longitudinal direction of the substrate web. In addition to static printing, the statically printed substrate web is printed dynamically with a variable print image in the area of a printing form-free printing device of the rotary printing press such that the print format of the printing form-free printing device extends in at least some sections over at least two statically printed pages.
    • 公开了一种用于在旋转印刷机中印刷基材卷材的方法。 要印刷的基材卷材通过基于印刷版的印刷单元输送,以便用印刷图像对印刷图像进行静态印刷,印刷图像对于印刷作业的印刷版本而言不会改变,使得至少印刷一个静态印刷页面 在成型圆筒的每转一次的基材卷材的纵向方向上,并且多个静态印刷页面沿着基材卷材的纵向印刷在基材卷材上。 除了静态印刷之外,在旋转印刷机的无印刷版印刷装置的区域中,动态地印刷静态印刷的基材卷材,其中可变的印刷图像使印刷无印刷装置的印刷格式延伸 至少在两个静态打印页面上的某些部分。
