摘要:
Reaction products of maleic anhydride and/or itaconic anhydride with one or more olefinically-unsaturated fatty compounds as compatibilizers for cellulose/plastic composites.
摘要:
The invention relates to a process for the production of plastics containing amide groups with elimination of CO.sub.2 by reaction of polyfunctional isocyanates, carboxylic acids and, optionally, alcohols in the presence of tertiary amines, more particularly heteroaromatic amines. The heteroaromatic amines preferably contain another heteroatom and/or substituents having +I and/or +M effects. The reaction preferably starts at room temperature. Fine-cell foams having an acid value of less than 40 and a density of at most 150 g/l can be produced in short reaction times at room temperature without any need for additional blowing agents.
摘要:
The invention relates to the use of compounds containing polyether chains prepared by reaction of epoxidized C.sub.10-22 carboxylic acid derivatives with polyalkylene glycols having average molecular weights of 100 to 2,000 and/or certain alkoxylated aliphatic compounds for the removal of printing inks from printed wastepaper and/or paper circuit waters.
摘要:
The invention relates to the use of reaction mixtures containing polyester polyols which have been obtained by ring opening of epoxidized esters with carboxylic acids, as polyol component, optionally in admixture with polybutadiene diol, in the production of solid polyurethane materials by casting.
摘要:
The invention relates to a polymer composition, comprising at least one thermoplastic polymer, at least one pigment or at least one filler or a mixture thereof and at least one diester of a linear diol having 2 to 8 C-atoms with a linear or branched, saturated or unsaturated monocarboxylic acid having 6 to 44 C-atoms, wherein the fraction of diesters comprising different fatty acid radicals in a molecule is less than 10% by weight with regard to the total amount of diesters.
摘要:
The present invention relates to a process for the preparation of an ester comprising an after-treatment of the ester to give an ester in granule form of defined particle size distribution, a device for carrying out this process, a process for the preparation of a thermoplastic composition comprising the ester prepared according to the invention, a process for the production of a shaped article comprising the ester according to the invention or the thermoplastic composition according to the invention, a process for the production of a packed product, a process for the production of an at least partly coated object, and uses of the esters according to the invention as an additive in various compositions.
摘要:
The present invention relates to a process for the preparation of an ester in a reactor, wherein at least a portion of the process components is led in a delivery stream outside the reactor over a heat transfer surface as a film, the ratio of the delivery stream to the heat transfer surface being in a range of from 0.25 to 3 m/h, a device, a process for the preparation of a thermoplastic composition comprising the ester prepared according to the invention, a process for the production of a shaped article comprising the ester according to the invention or the thermoplastic composition according to the invention, a process for the production of a packed product, a process for the production of an at least partly coated object, and uses of the esters according to the invention as an additive in various compositions.
