Patent ID: 8470306

Claim:
A crosslinked organopolysiloxane comprising: organopolysiloxane units; and building blocks which link the organopolysiloxane units; wherein the building blocks are identical or different blocks of the formula (I): —CH 2 —CH 2 -(G) n O(EO) x (PO) y (XO) z — (I); where G=divalent organic radical; where EO═(C 2 H 4 O) where PO═(C 3 H 6 O) where XO═(C 2 H 3 R 5 O) where n=1 to 16; where x=2 to 50; where y=0 to 50; where z=0 to 10; and where R 5 =independently of one another, identical or different radicals selected from the group consisting of: alkyl radicals having 2 to 16 carbon atoms, which are optionally interrupted by ether functions; alkaryl radicals having 7 to 18 carbon atoms; and aryl radicals having 6 to 16 carbon atoms; and where the building blocks of the formula (I) are directly linked to an Si atom at both linkage points, so that there is an SiC bond at one linkage point and a COSi bond at the other linkage point.
