Abstract: The invention relates to a process for producing flowable polyorganosiloxane compositions which comprise reinforcing filler and vulcanize at room temperature or elevated temperature to produce elastomers and retain their flowability on addition of polar additives.

Abstract: Condensation-crosslinking, room-temperature vulcanizing silicone rubber compositions A which contain additives B selected from the group consisting of sterically hindered phenols, sterically hindered bisphenols, sterically hindered thiobisphenols, zinc dialkyl dithiophosphates, zinc diaryl dithiophosphates, aromatic amines, sterically hindered amines or preparations containing the abovementioned substances, these additives optionally being present in the compositions A either individually or in any mixtures and mixing ratios with respect to one another.

Abstract: Compositions having liquid crystal phases which contain at least one component consisting of an organopolysiloxane having mesogenic molecules chemically bonded thereto as side chains which are obtained by grafting vinyl-substituted mesogenic molecules to an organohydrogenpolysiloxane. The organopolysiloxane backbone may also carry different molecules, such as nematogenic and cholesterogenic or chiral molecules, as side chains.
