Compositions which crosslink to form elastomers and are based on

Compressible, sulfur-containing silicone rubber

The present invention relates to compositions which crosslink to give elastomers, comprising;

Liquid silicone rubber with improved compression set

A method for impregnating organic fibers which comprises applying a composition containing (1) an organopolysiloxane having silicon-bonded condensable groups and containing diorganosiloxane units in which the two SiC-bonded organic radicals are monovalent hydrocarbon radicals and also contains two monovalent SiC-bonded radicals having a basic nitrogen group; (2) an organopolysiloxane having at least 3 Si-bonded hydrogen atoms per molecule; and (3) a catalyst which promotes the condensation of the silicon-bonded condensable groups, in which the SiC-bonded radicals having a basic nitrogen group are present in the organopolysiloxane (1) as monoorganosiloxane units and as diorganosiloxane units.

Method for impregnating organic fibers

A process for preparing organofunctional organopolysiloxanes which comprises reacting a cyclic diorganopolysiloxane with a silane having a SiC-bonded monovalent organic radical with at least one functional group and at least one SiOC-bonded monovalent hydrocarbon radical which can be substituted by an ether oxygen atom, or with an oligomer of such a silane having a maximum of 10 silicon atoms per molecule, in the presence of a quaternary ammonium hydroxide.
