Abstract: A molding, preferably a film-like molding, is produced by a process which comprises the following stage:

Abstract: This invention provides an apparatus and method for injecting an additive directly into a polymer melt stream. The method comprises supplying a melt flow of a polymeric host material to a die assembly having a thin-plate assembly and injecting at least one additive into at least one predetermined location in a cross-section of the melt flow of the polymeric host material while the melt flow passes through the die assembly. The method achieves uniform dosing of the one or more additives in the extrusion direction in the polymeric host material without homogeneously mixing the one or more additives and the polymeric host material. The apparatus for directly injecting one or more additives into a polymer melt stream comprises a pumping system, a die assembly having a thin-plate assembly, and a distribution line.

Abstract: Polymers of vinylaromatic compounds are prepared at from -80 to 150.degree. C. in the presence of metallocene catalyst systems by a process in which polymerization is carried out in one stage with the use of a closely intermeshing twin-screw extruder having corotating screws.

Abstract: Process for preparing copolymers of aromatic vinyl compounds at -80 to 150.degree. C. in the presence of metallocene catalyst systems using a corotating, closely intermeshing twin-screw extruder for polymerization.

Abstract: Mixtures of high molecular weight polyisobutylene and thermoplastic polymers are prepared in an extruder by a process in which meterable, high molecular weight polyisobutylene is first metered into the extruder and homogenized in at least one kneading stage, heated and subjected to controlled molecular weight degradation and the thermoplastic polymer is then introduced into the polyisobutylene melt by means of a side feed and is subsequently homogenized together with said melt. The novel process is particularly suitable for the preparation of mixtures of high molecualr weight polyisobutylene and polyethylene.

Abstract: A terminal strip is described, of the type that includes connector modules that can be mounted end-to-end on a circuit board to provide a strip having the desired number of contact positions, which minimizes the number of separate connector modules that must be mounted, which minimizes the number of different module lengths that must be manufactured, and which increases the stability of the connector modules. Where rear modules are mounted to the rear of the connector front modules, the front and rear modules are laterally offset. Different length modules, that is, modules with different numbers of columns of contact positions, are manufactured, with the smallest module having a predetermined number of columns, the second smallest size having twice as many columns as the smallest, and the third largest size having four times as many columns as the first. Similar lengths of rear modules are provided.
