The invention concerns polysiloxane compounds which contain the following components: 1. organopolysiloxane with at least two aliphatic double bonds in the molecule; 2 organopolysiloxane with at least two Si&mdash;H groups in the molecule; 3. noble metal catalyst; and 4. hydrophilic modifier of general formula (I) &lsqb;H,C&boxH;CH&mdash;A,&mdash;(A,),&mdash;X&rsqb;,B (I), in which A,, A,, X, B, m and n have the meanings given in claim 1. The polysiloxane compounds are stable during storage and are used as dental casting compounds.

Polysiloxane compound which is stable during storage and produces vulcanisates which can be permanently wetted with water

Organopolysiloxane compositions which can be crosslinked to give

This invention relates to organosiloxanes which have SiC-bonded ester groups and contain at least one unit of the general formula: ##EQU1## is which R represents the same or different monovalent hydrocarbon radicals having from 1 to 12 carbons atoms, which are free of aliphatic unsaturation and which may contain one ether oxygen atom; R' represents hydrogen or a methyl group (CH.sub.3) and a is O, 1 or 2. These organosiloxanes can be prepared by hydrolyzing or co-hydrolyzing silanes of the general formula:
