Abstract

Described herein is a process for the production of moldings made of porous material impregnated with polysulfide, the process including the following steps:(a) insertion of the porous material into a mold;(b) introduction of liquid polysulfide into the mold at a flow velocity within the porous material in the range from 0.5 to 200 cm/s;(c) cooling of the polysulfide to a temperature below the melting point of the polysulfide; and (d) removal of the porous material impregnated with the polysulfide.
