Abstract: The invention relates to a module for absorbing energy from an impact to which the module (3) has been subjected, via deformation, comprising a core (5) made of a polymer foam with a density of at most 0.2 g/cm3 and with a compressive modulus of elasticity of at most 200 MPa measured to DIN EN 826, wherein the core (5) has an at least to some extent enclosing shell (7) made of a polymer material, and/or comprises an insert (15) made of a polymer material, where the density of the polymer material of the shell (7) and/or of the insert (15) is at most 2.0 g/cm3 and its tensile modulus of elasticity is at least 700 MPa, measured to DIN EN ISO 527.

Abstract: Preparations with enlarged surface comprising an active ingredient and an amphiphilc copolymer, wherein the copolymer comprises at least one polyether-containing graft polymer. The preparations are partially or completely foamed. Processes for producing the preparations are also described, including processes comprising extrusion of a melt impregnated with a physiologically acceptable volatile blowing agent.

Abstract: Process for the production of nanoporous foamed active substance-containing preparations, wherein the active substance is present embedded in a pharmaceutically acceptable polymer, wherein, in stage a) loading of a polymeric molding composition or a polymer melt with a propellant is effected at a pressure and at a temperature at which the propellant is in the supercritical state, in stage b) heating of the laden polymer molding compound or melt is carried out under pressure at a temperature which lies in the range from ?40 to +60° C., preferably ?20 to +55° C., and especially preferably 0 to +50° C. around the glass transition temperature of the unladen (prior to loading) polymeric molding compound and in stage c) a depressurization of the polymeric molding compound or melt laden in stage a) and heated under pressure in stage b) is effected out with a depressurization rate in the range from 15,000 to 200,000 MPa/sec.

Abstract: Process for the production of nanoporous polymer foams, comprising the stages a) loading of a single-phase, thermoplastic polymer melt with a gas under a pressure and at a temperature at which the gas is in the supercritical state, b) heating of the laden polymer melt to a temperature which lies in the range from 40° C. under to 40° C. over the glass transition temperature of the unladen polymer melt determinable by means of DSC according to DIN-ISO 11357-2 at a heating rate of 20 K/min, c) depressurization of the polymer melt loaded in stage a) and heated in stage b) with a depressurization rate in the range from 15,000 to 200,000 MPa/sec, and the nanoporous polymer foams with a cell count in the range from 1,000 to 100,000 cells/mm and a density in the range from 10 to 500 kg/m3 obtainable according to the process.
