Polydiorganosiloxanes of the general formulaR&#x2014;(OSiR)OH&#x2003;&#x2003;(I)are prepared by reacting hexaorganocyclotrisiloxanes of the formula(RSiO)&#x2003;&#x2003;(II)with alcohols of the formulaR&#x2014;OH&#x2003;&#x2003;(III)where each R is the same or different and is a monovalent, optionally substituted hydrocarbon radical,

Preparation of polydiorganosiloxanes

The invention relates to aliphatically unsaturated organosilicon compounds having 2 to 17 silicon atoms, to processes for their preparation and to their use in crosslinkable organopolysiloxane compositions, especially in compositions which can be crosslinked peroxidically or by hydrosilylation.

Organosilicon compounds, processes for their preparation, and their use in crosslinkable organopolysiloxane compositions

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.
