  • Patent number: 11910931
    Abstract: It is a feature of a porous body (10, 20) comprising a three-dimensional network of node points (200) joined to one another by struts (100), and a void volume (300) present between the struts (100), that the struts (100) have an average length of ?200 to ?50 mm, the struts (100) have an average thickness of ?100 ?m to ?5 mm, and that the porous body has a compression hardness (40% compression, DIN EN ISO 3386-1: 2010-09) in at least one spatial direction of ?10 to ?100 kPa. The porous body according to the invention combines the advantages of a conventional mattress or cushion with ventilatability which results from its porous structure and is not achievable in conventional foams. The invention further relates to a method of producing such a porous body (10, 20) and to an apparatus comprising said body (10, 20) for supporting and/or bearing a person.

  • Patent number: 11905360
    Abstract: The invention relates to a method for producing a polymer comprising the following steps: (A) depositing a radically cross-linkable resin, obtaining a radically cross-linked resin; and (B) treating the radically cross-linked resin under conditions which are sufficient to trigger a chemical reaction that is different from the radical cross-linking in the radically cross-linked resin. The radically cross-linkable resin comprises a curable component, in which there are NCO groups, olefinic C?C double bonds and epoxide groups, and the chemical reaction in the radically cross-linked resin that is different from the radical cross-linking is the reaction of NCO groups and epoxide groups to form oxazolidinone groups.
