Abstract: A process is described for the preparation of polymeric networks having superstructures, resulting from the use of liquid-crystalline, (poly)functional units, characterized in that build-up into polymers is carried out by the polymerization, polyaddition or polycondensation process within the liquid-crystalline, preferably nematic, temperature range of the (poly)functional units, having a liquid-crystalline character, used for building up the networks.Polymeric networks which are accessible by this process, and the use thereof, are also claimed.

Abstract: The use of acyl phosphanoxides of the formula I ##STR1## in which each R, independently of the others, can denote linear or branched C.sub.1 -C.sub.12 -alkyl, cycloalkyl or optionally mono- or poly-C.sub.1 -C.sub.12 -alkyl-substituted, alkoxy-substituted or halo-substituted aryl or phenyl,for improvement of the mechanical properties in ABS moulding materials.

Abstract: The invention relates to the use of novel N,N-disubstituted arylamines containing polymerizable groups as hardening accelerators for polymerizable compositions based on unsaturated polyester resins, in particular for trowelling and water compositions.

Abstract: Compounds of the formula ##STR1## are suitable as curing accelerators which can be incorporated into ethylenically unsaturated, cold-curable resins.

Abstract: A method of reducing the NO.sub.x content in combustion gases by introducing secondary fuel, via a liquid carrier, into the combustion chamber at a location disposed between the supply of fuel and air for the primary combustion, and the supply of secondary air for the complete combustion.

Abstract: Compounds of the formula ##STR1## are suitable as curing accelerators which can be incorporated into ethylenically unsaturated, cold-curable resins.

Abstract: Compounds of the formula ##STR1## in which R represents hydrogen or a methyl group,Y.sup.1 represents an optionally branched alkylene radical with 1 to 6 C atoms,Y.sup.2 represents an optionally branched alkylene radical with 2 to 8 C atoms,X denotes oxygen or an --NH-- group,R.sup.1 and R.sup.2 are identical or different and denote hydrogen, or an alkyl, alkenyl, cycloalkyl, cycloalkenyl, aryl, aralkyl or alkylaryl group which has 1 to 11 C atoms and is optionally substituted by one or more,hydroxyl, amino, epoxide, urethane, urea, ester or ether groups, orR.sup.1 and R.sup.2 together form a 3-membered to 6-membered ring, which optionally contains nitrogen, oxygen or sulphur as hetero-atoms,R.sup.3 has the meaning of R.sup.1 or represents a group ##STR2## or R.sup.2 and R.sup.3, together with the ##STR3## group, form a 5-membered or 6-membered ring, which optionally contains oxygen as a further hetero-atom, andR.sup.4 and R.sup.

Abstract: High frequency electrical cable is provided in accordance with the teachings of the instant invention wherein a plurality of conductors for transmitting information are contained in a common sheathing. Each of the plurality of conductors takes the form of a central core of insulating material upon which a layer of conductive material is rigidly disposed. The thickness of the layer of conductive material is such that current penetration is substantially independent of frequency within a given frequency range. Therefore, within this frequency range the attenuation characteristics of the resulting cable are substantially independent of frequency.
