The invention relates to thermally stable and UV-stable polyamide molding compounds containing colloidal copper formed in situ and to a process for their production.

Thermally stable copper-containing polyamide molding compounds

In order to improve the adhesion of coatings, especially metal coatings, to the surfaces of plastic components, the latter are pretreated in low-pressure plasma with a process gas containing sulphur hexafluoride (SF.sub.6) which is substantially free of oxygen, the plastic surfaces being kept free of fluorine deposits or inclusions during the pretreatment.

Process for pretreating surfaces of plastic items

The invention relates to the use of nucleus-brominated phthalic acid derivatives, optionally in combination with polyalkylene oxides corresponding to formula (V) ##STR1## in which R is H, C.sub.1-6 alkyl, tetrahydropyranyl or a silyl group,

Use of nucleus-brominated phthalic acid anhydride for stabilizing

The apparatus is based on a standard grindometer block comprising a longitudinally extending sample channel of steadily increasing depth which is filled with the paint to be investigated and then stripped and smoothed with a doctor blade. Instead of being visually evaluated, the paint surface is subjected to automatic objective evaluation in an optoelectronic apparatus comprising a light source with a focussing lens for producing a light spot on the paint surface to be investigated, a dark-field lens comprising an objective for picking up the scattered light emanating from pigment particles in the vicinity of the light spot and an aperture diaphragm for eliminating the light directly reflected at the paint surface, a photoreceiver connected to an evaluation circuit for detecting, recording and further processing the scattered light signals and a scanner for longitudinally scanning the sample channel.

Apparatus for determining the size distribution of pigment particles in

The invention relates to flameproofed non-drip polyamide molding compounds which contain certain quantities of

Flameproofed non-drip polyamide molding compounds

The present invention relates to a sensor with a novel construction for a detection method of molecules labelled with fluorescent dye for detecting these dissolved substances or analytes by energy transfer with a simple fluorescence technique and increased sensitivity in the detection as well as versatile use for different tasks and the possibility of reproducible preparation of films bound to solid surfaces.

Optical biosensor and method of use

This invention relates to synthetic resin bodies of thermoplastic polyarylene sulphides and/or of thermoplastic polycarbonates coated with zinc sulphide (ZnS).
