A dye acceptor element for thermosublimation printing comprising a support and a dye acceptor layer consisting essentially of polycarbonate arranged on the support, the polycarbonate containing 30 to 95% by weight aromatic carbonate structural units corresponding to formula I

Dye acceptor element for thermosublimation printing

The new aromatic polyethers containing ester groups, which are distinguished by high dimensional stability, may be used for the production of all kinds of moulded products as well as for the preparation of block copolymers of aromatic polyether segments and segments of other thermoplastic polymers.

Aromatic polyethers containing ester groups

The invention relates to the use of salts of sulfosuccinic acid esters as internal antistatic agents, take-off and winding aids for transparent cast films of polycarbonates, to a process for the production of cast polycarbonate films and to the cast polycarbonate films themselves containing salts of sulfosuccinic acids and also to the use of the new cast polycarbonate films in the electrical field and optical field.

Alkali or alkaline earth salts of sulfosuccinic acid esters as internal

The present invention relates to a process for the production of porous, and particularly macroporous, membranes. The membranes produced by the process are highly absorbent and can therefore be employed, as supporting matrices for test strips. These test strips can be used for the detection of substances to be analyzed in a liquid.

Monofunctional polyethers having hydroxyl groups contain as built-in terminal groups or monomers

Polyethers, process for their preparation and lubricants containing

Composite membranes of a macroporous filler-containing membrane of at least two incompatible polymers and a pore-free polyurethane membrane applied there to exhibit an improved action in the removal of benzenes optionally suhstituted by lower alkyl radicals, hydroxyl, chlorine or bromine from their mixtures with aliphatic and/or cycloaliphatic hydrocarbons, alcohols, ethers, ketones and/or carboxylic acid esters or from effluent.
