    Abstract: The present invention relates to a process for producing flame-retardant porous materials comprising the following steps: (a) reacting at least one polyfunctional isocyanate (a1) and at least one polyfunctional aromatic amine (a2) in an organic solvent optionally in the presence of water as component (a3) and optionally in the presence of at least one catalyst (a5); and then (b) removing the organic solvent to obtain the organic porous material, where step (a) is carried out in the presence of at least one organic flame retardant as component (a4), where this flame retardant is soluble in the solvent. The invention further relates to the porous materials thus obtainable, and also to the use of the porous materials for thermal insulation.

    Abstract: A transport container for transporting an object includes an object location to receive the object and a vacuum insulation panel (VIP) to thermally insulate the object location. A sensor unit in the VIP provides a panel condition signal that corresponds to a measurement value of a physical property of the VIP. The physical property influences temperature of the object. A short-distance transmitter unit transmits a first coding of the PCS inside the Container, a long-distance transmitter unit transmits a second coding of the PCS to a remote server for processing the PCS. The server determines a representation of an operation state of the transport container, wherein the operation state is related to the temperature of the object. The material of the VIP is classified and differentiated so that transmitting parameters depend on the material.
