摘要： A shell-and-tube heat exchanger, for removing volatile substances from a polymer solution by degasification, includes a bundle of tubes arranged vertically and parallel to each other in a shell chamber through which a fluid heat-transfer medium flows. The upper end of each tube is fixed in an upper tube sheet and the lower end of each tube is fixed in a lower tube sheet, and the polymer solution flows through the tubes in the direction of gravity. One feature is that a multilayer woven wire fabric is attached to the top of the upper tube sheet. The finest meshed layer of the fabric has a mesh width of 50 μm to 1000 μm. The invention also relates to a method for removing volatile substances from a polymer solution by degasification in a shell-and-tube heat exchanger and use of the shell-and-tube heat exchanger.

摘要： A novel, optically transparent, isotropic molding for optical purposes which is free of orientation birefringence consists of a mixture of polyphenylene ethers, vinylaromatic polymers and additives. The novel molding contains traces of novel diphenoquinone and/or diphenohydroquinone derivatives as additives and may also contain novel ammonium salts of sulfuric acid half esters of diphenohydroquinones as further additives. The novel molding has a yellowness index (YI) of from 40 to 90. It can be produced in a simple manner by injection molding processes. The novel molding in the form of a circular disk having a central hole is very useful as a dimensionally stable substrate of audio compact disks (CD), audiovisual compact disks (CDV), laser-optical computer disks and magneto-optical computer disks, and data media of this type which contain these novel dimensionally stable substrates have particularly advantageous performance characteristics.
摘要翻译：用于光学目的的新型光学透明的各向同性模制物，其不含取向双折射，由聚苯醚，乙烯基芳族聚合物和添加剂的混合物组成。该新型成型物含有痕量的新颖的联苯醌和/或二苯氢醌衍生物作为添加剂，并且还可以含有二苯氢醌的硫酸半酯的新型铵盐作为其它添加剂。新型成型品的黄色指数（YI）为40〜90。可以通过注塑成型工艺简单地生产。具有中心孔的圆盘形式的新颖模制作为音频光盘（CD），视听光盘（CDV），激光光学计算机盘和磁光计算机盘的尺寸稳定的基板是非常有用的，以及包含这些新颖的尺寸稳定的基板的这种数据介质具有特别有利的性能特性。
