The present invention is directed to the use of polymer blend films consisting of polycarbonate and polyalkylene terephthalate supports for diagnostic test strips.

Use of polymer blend films as supports for diagnostic test strips

A process for the production of optically isotropic extrusion films is disclosed. Accordingly in a first process step a thermoplsatic resin is extruded to form a film having a thickness below 600 .mu.m. The second process step entails

Films from aromatic polyesters and from aromatic polyestercarbonates are excellently suitable for preparing printing ribbons, in particular for thermal and electrothermal recording processes.

This invention relates to carbon-containing moulded bodies based on thermoplastic polycarbonates and thermoplastic polyalkylene terephtalates with an addition of carbon black and graphite and to a process for the production of these moulded bodies.

Metal-plastic laminates are prepared by coating a metal component with a polyurethane adhesion promoter in dissolved or dispersed form, drying the liquid phase and coating with the melt of a thermoplastic by the extrusion coating process.

Films from aromatic polyesters and from aromatic polyestercarbonates are excellently suitable as electrically insulating films, for example as dielectric for capacitors and as conductor track films.

Use of films of polycondensates

This development is concerned with aromatic thermoplastic polycarbonates with special chain terminators which give the polymers enhanced hydrolysis resistance and impact toughness. These chain terminators are alkyl substituted monohydroxy phenyls in which each phenyl is substituted by one alkyl group having 8 or 9 carbon atoms and about 47 to 89% of its hydrogen atoms trisubstituted on carbon atoms with up to about 20% of the substituents in the ortho position and the balance at the para position. This development is also concerned with a process for synthesizing such polymers by using such chain terminators as reactants in generically known synthesis methods for polycarbonates.

Moulding compositions for the production of mouldings with fire-retarding properties and with a polytriazine structure, comprising mixtures of (A) 10 to 90% by weight of at least one polyfunctional, aromatic halogen-free cyanic acid ester or a prepolymer thereof which is still fusible or soluble in solvents, and (B) 10 to 90% by weight of at least one polyfunctional, aromatic halogen-containing cyanic acid ester or a prepolymer thereof which is still fusible or soluble in solvents.

Moulding compositions of mixtures of halogen-containing and halogen-free

Aromatic cyanic acid esters are obtained by an improved process. Optionally substituted mononuclear phenols or polynuclear phenols optionally interrupted through bridge members such as ##EQU1## and/or divalent hydrocarbon bridges are condensated in form of an aqueous phenolate solution with cyanogen halide dissolved in organic solvents in the presence of catalytic quantities of a tertiary amine in a highly disperse system (two phase boundary reaction). The cyanic acid esters obtained are highly pure and stable.
