A mixture comprising fine meltable polymer particles, a particulate material with a sorptive action and a fluid is compressed in a molding tool through which a hot gas flows. The gas is at a temperature above that of the fluid evaporation temperature and both evaporates the fluid, whose evaporation temperature is no greater than the melting point of the polymer, and melts the polymer. <??>A mixture comprising fine meltable polymer particles, a particulate material with a sorptive action and a fluid is compressed in a molding tool through which a hot gas flows. The gas is at a temperature above that of the fluid evaporation temperature and both evaporates the fluid, whose evaporation temperature is no greater than the melting point of the polymer, and melts the polymer. The same process may be carried out without addition of a fluid. |
