Flameproofed non-drip polyamide molding compounds

Process for rendering a plastic identifiable by adding 5 to 10,000 ppb of a fluorescent marker to the plastic during or after is manufacture.

Process for identifying plastics by addition of fluorescent dye

By processing fibres and filaments of thermotropic polymers from anisotropic melt, films and mouldings having predeterminable properties are formed.

Process for the production of mouldings and films from thermotropic

Thermotropic aromatic polyesters which contain 3,3'-diphenyl-4,4'-dihydroxydiphenyl radicals as diphenol radicals can be processed by thermoplastic methods without decomposition, in spite of the high heat distortion resistance.

Thermotropic aromatic polyester from 3,3'-diphenyl-4,4'-dihydroxy

Fully aromatic polyesters which contain 3-phenyl-4,4'-dihydroxybenzophenone radicals and/or 3-phenyl-3',4-dihydroxybenzophenone radicals as condensed units possess high mechanical properties but can still be processed without difficulties by a thermolastic method.

Thermotropic aromatic polyesters having high mechanical properties and

This invention relates to the production and use of coating powders based on saponified ethylene/vinyl acetate copolymers (EVA copolymers) modified with polyalkyl (meth) acrylates. Coatings and films produced from these coating powders are distinguished by the flexibility and elasticity thereof, especially at low temperatures.

Coating powder based on saponified ethylene/vinyl acetate copolymers and

Pulverulent coating materials consisting of saponified ethylene vinyl acetate copolymers and, as cross-linking agents, polycarbodiimides and/or polyuretone imines.
