The invention relates to a process for the production of thermoplastic moulding compounds, in particular for the production of acrylonitrile-butadiene-styrene (ABS), wherein at least a first reagent () and a second reagent () of the thermoplastic moulding compounds are fed to a loop conduit () which comprises a static mixer (), wherein the reagents () are pressed in loops through the loop conduit () and passing the static mixer (), whereby the reagents () are dispersed to form a dispersion () in the static mixer (). The invention also relates to a thermoplastic moulding compound that is produced by the inventive process.

Process for the production of thermoplastic moulding compounds

The invention relates to a process for the production of thermoplastic moulding compounds, in particular ABS, wherein at least a first reagent () and a second reagent () of the thermoplastic moulding compounds are fed to a gear pump () which comprises a housing and at least a first gear wheel that is rotatable relative to the housing about a first axis, and a second gear wheel that is rotatable relative to the housing about a second axis, wherein a loop conduit () is provided, and wherein the reagents () are pressed in a loop through the loop conduit () and passing the gear wheels, whereby the reagents () are dispersed to form a dispersion () in the gear pump (). The invention also relates to a thermoplastic moulding compound that is produced by the inventive process.

A process for the surface treatment of moldings based on liquid crystalline polymers with acidic or alkaline reagents includes using the reagents in a solvent which is an organic solvent to an extent of not less than 60% by weight.

A laser-optical write and read process whereby a thermally alterable recording layer which contains liquid-crystalline compounds in homogeneous planar orientation and forms part of a multilayer, sheet-like recording material is written by means of a write laser beam with analogue or digital data in the form of thermally altered areas, whereafter the written data are read by means of a read laser beam, including: analyzing the light transmitted or reflected by the recording material, and reading the data by determining the polarization-optical contrast between the thermally altered and the unaltered areas and/or utilizing for this purpose the interference of the light rays which form from the laser lightwaves in a Gaussian intensity distribution owing to the different phase velocities of the light in the center of thermally altered areas on the one hand and their thermally unaltered surroundings on the other.
