Claim:
An α-silyl terminated polydiorganosiloxane having the following general formula (I): wherein the radicals R 1 are selected from the group consisting of straight-chain aliphatic radicals, branched aliphatic radicals, cycloaliphatic radicals, aryl radicals, and aralkyl radicals, each radical R 1 containing 1 to 12 carbon atoms and optionally one or more heteroatoms and optionally being substituted with halogen, the radicals R 1 being identical or different within the polydiorganosiloxane; the radicals R 2 and R 3 , which are identical or different, are selected from the group consisting of straight-chain aliphatic radicals and branched aliphatic radicals; the radicals R 4 and R 5 , which are identical or different, are selected from the group consisting of straight-chain aliphatic radicals, branched aliphatic radicals, OR 2 and OR 3 , wherein R 2 and R 3 are defined as above; the radicals X and Y, which are identical or different, are selected from the group consisting of O, S, PR 8 and NH, wherein R 8 is selected from the group consisting of H, —(C═O)NH—R 9 , —(C═O)—R 9 and —(SO 2 )—R 9 , wherein R 9 is selected from the group consisting of aliphatic radicals, cycloaliphatic radicals, and aryl radicals, each radical R 9 containing 1 to 12 carbon atoms and optionally containing one or more heteroatoms; the radicals R 6 and R 7 , which are identical or different, are selected from the group consisting of straight-chain aliphatic radicals with 1 to 12 carbon atoms, branched aliphatic radicals with 1 to 12 carbon atoms, 5-membered and 6-membered cycloalkyl radicals containing one or more heteroatoms and optionally containing one or more double bounds, aryl radicals, aryl radicals containing one or more heteroatoms, ═C═O, and (C═O)R 10 , wherein R 10 is selected from the group consisting of Z—R 11 , wherein Z is selected from the group consisting of S, O, PR 8 and NH and R 11 is selected from the group consisting of straight chain aliphatic radicals with 1 to 12 carbon atoms and branched aliphatic radicals with 1 to 12 carbon atoms; n is from 10 to 10000; and salts obtained by reaction of said polydiorganosiloxane with organic or inorganic acid, and products obtained by quaternization reaction of said polydiorganosiloxane.
