The present invention relates to (co)polymers which contain at least one repeat chain unit of the general formula (1) or (2) and optionally repeat units of the general formula (3), ##STR1## in which L.sup.1 and L.sup.2 mutually independently mean a photoluminescent residue, to a process for the production thereof, to the use thereof in electroluminescent devices and to the electroluminescent devices.
摘要:
This invention relates to (co)polymers which contain at least one repeat chain unit of the general formula (1) or (2) and optionally repeat units of the general formula (3), ##STR1## in which L.sup.1 and L.sup.2 denote a photoluminescent residue, wherein the proportion of structural units of the formulae (1) and/or (2) is in each case 0.5 to 100 mol. % and of (3) is 0 to 99.5 mol. % and the molar percentages add up to 100, to the use thereof for the production of electroluminescent arrangements and to the electroluminescent arrangements.
摘要:
This invention relates to decomposable polyamide masses for packaging materials containing 5 to 25% by weight of an addition of linear, oligomeric aliphatic polyesters or polycarbonates with molecular weights from 800 to 4000. These additives preferably consist of polyesters of aliphatic diols and dicarboxylic acids having up to 10 carbon atoms or aliphatic carbonates having up to 10 carbon atoms.The use of such mixtures for easily degradable, decomposable polyamide packages is also claimed, in particular in the form of films or thin walled injection moulded parts for (food) packaging.
