摘要:
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.
摘要:
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[--O--diphen--O--CO--] (I)in which diphen is the residue of a diphenol containing 6 to 30 and preferably 12 to 24 carbon atoms, and 70 to 5% by weight aliphatic polyether carbonate structural units corresponding to formula II[--O--polyether--O--CO--] (II)in which polyether is the residue of an aliphatic polyether diol having a molecular weight Mn of 600 to 20,000, is distinguished by high color density and a minimal tendency towards adhesion.
摘要:
Monofunctional polyethers having hydroxyl groups contain as built-in terminal groups or monomers(a) 1 to 30% by weight of one or more C.sub.4 - to C.sub.24 -alkylmonophenols,(b) 1 to 30% by weight of one or more C.sub.8 - to C.sub.24 -monoalkanols,(c) 1 to 30% by weight of one or more C.sub.10 - to C.sub.20 -1,2-epoxyalkanes and(d) 45 to 80% by weight of propylene oxide or a lower alkylene oxide mixture consisting mainly of propylene oxidethe sum of components (a) to (d) adding up to 100% by weight, and have average molecular weights of 600 to 2,500.These polyethers are prepared by anionic epoxide polymerization and used as lubricants and components of lubricants.
摘要:
The present invention relates to the combination of aminophenylamidine derivatives with cyclic depsipeptides, to products comprising this combination, and to the use of these active substances in combination for controlling endoparasites in humans and in animals.
摘要:
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.
摘要:
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.
摘要:
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.
