  • Process for preparing nano-or microparticles comprising a carrier-polymer and one or more biologically active ingredients
    Patent number: 11819576
    Abstract: A process can be used for preparing nano- or microparticles containing a carrier-polymer and a biologically active ingredient. The process is a solvent emulsion process involving an organic phase (OP) and an aqueous phase (AP) to form an emulsion. In the case of an oil-in-water emulsion (O/W), the organic phase (OP) contains the biologically active ingredient dissolved or dispersed therein. Alternatively, in the case of a water-in-oil emulsion (W1/O), the aqueous phase (AP) contains the biologically active ingredient dissolved or dispersed therein. The organic phase (OP) is saturated with the salt-containing aqueous phase (AP) and vice versa.

  • PEI particle foams for applications in aircraft interiors
    Patent number: 11814499
    Abstract: Polymer foams based on polyetherimides (PEIs) fulfill the legal specifications demanded by the aviation industry for aircraft interiors. Specifically, the demands on fire characteristics, stability to media and mechanical properties constitute a great challenge here. According to related art, suitable polymer foams are produced as semi-finished products. Reprocessing to give shaped articles is uneconomic in terms of time and material exploitation, for example by virtue of large amounts of cutting waste. The material is suitable in principle and can be processed to give particle foam mouldings. These mouldings can be produced without reprocessing in short cycle times and, hence, economically. Furthermore, this gives rise to new means of functional integration, for example by direct incorporation of inserts etc. in the foam, and with regard to freedom in terms of design.

  • Variable and self-regulating permeate recycling in organophilic nanofiltration
    Patent number: 11806669
    Abstract: The invention provides an improvement in terms of control and process technology for a method of continuous removal of a component from a liquid mixture using a membrane unit comprising at least one membrane stage. The improvement is that a portion of the overall permeate stream is recycled to the feed vessel and/or beyond the feed vessel but upstream of the conveying device, and the remainder of the overall permeate stream is removed, with the recycled permeate having a higher concentration of the component to be separated off than the removed permeate. The presently disclosed method can especially be used for separation of a homogeneously dissolved catalyst from a liquid reaction mixture.

  • Plastic material for printing by dye diffusion thermal transfer printing
    Patent number: 11807025
    Abstract: A plastic material is useful as an ink receiver or printing medium in dye diffusion thermal transfer printing, wherein the plastic material has a polyamide component (a), and a (co)-polyamide (b) based on ether units and amide units. This plastic material can be used to make a layered structure. The layered structure can be used in dye diffusion thermal transfer printing. A security and/or valuable document with the layered structure can be obtained. Based on the finding that the (co)-polyamide (h) offers sufficient absorbency for the printing ink, the layer produced from the plastic material can be printed on by means of dye diffusion thermal transfer printing with a good color intensity.
