The manufacture of porous molded bodies by sintering of a mixture of powderous thermoplastic polymers and a liquid is described, the boiling point of the latter being at least equal to or higher than the sintering temperature. Sintering takes places in a mould, the process may be performed continuously and is suitable for the manufacture of porous molded bodies such as pipes, panels and the like which can be used as filter, gas distribution, air distribution, coalescing elements, as suction elements for oil, as carriers of active substances etc. |
