Abstract
A method of improving the efficient depletion of the siloxane oligomer present in organopolysiloxane moldings by using supercritical carbon dioxide gas, so that this reduction in siloxane oligomer content is accomplished without cracking of the moldings by regulating the pressure reduction to less than 40 Kg/cm.sup.2 per 1 hour during the release to atmospheric pressure.
