The invention relates to a process for the production of monomeric alkenylphenols from dihydroxydiphenylalkanes by thermal cleavage in certain solvents.
摘要:
Polymer composite material with biocide functionality, preferably for the use in agriculture, comprising at least one base polymer compound and at least one biocide active ingredient, wherein the biocide active ingredient is an organic biocide that can be emitted from the polymer composite material by diffusion and/or osmosis and method of its production.
摘要:
The invention provides moulded items made from thermoplastic polyurethanes (TPUs), in particular medical articles such as central venous catheters which contain a homogeneous distribution of antibiotic substances, a process for the preparation thereof and preparation of the active substance-containing TPUs.
摘要:
This invention relates to thermoplastic polyurethanes (TPUs) which contain pharmaceutical active ingredients in a homogeneous distribution, to a method of producing them, and to their use in medical articles. During the production of the TPUs, compounds having an antithrombotic or antibacterial effect are added to the monomer mixture.
摘要:
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.
