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.

A process for the production of moldings made of porous material impregnated with polysulfide, comprising 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, wherein after filling of the mold and during cooling, a pressure is applied to introduce further polysulfide into the mold.
