Claim:
Polysiloxanes of formula 1: M a D b D A c D B d D C e T f Q g (formula 1) where: M=[R 2 R 1 2 SiO 1/2 ] D=[R 1 2 SiO 2/2 ] D A =[R 1 Si(R 7 NHR 3 )O 2/2 ] D B =[R 1 SiR 4 O 2/2 ] D C =[R 1 SiR 5 O 2/2 ] T=[R 1 SiO 3/2 ] Q=[SiO 4/2 ] in which: R 1 in each occurrence independently represents identical or different linear or branched, saturated or unsaturated hydrocarbon radicals having 1 to 30 carbon atoms or else aromatic hydrocarbon radicals having 6 to 30 carbon atoms; R 2 in each occurrence independently represents R 1 , an alkoxy radical or a hydroxyl group; R 3 in each occurrence independently represents hydrogen or a hydrocarbon radical substituted with nitrogen atoms; R 4 in each occurrence independently represents identical or different linear or branched, saturated or olefinically unsaturated hydrocarbon radicals having 8 to 30 carbon atoms; R 5 in each occurrence is independently selected from the group consisting of: identical or different linear or branched, saturated or unsaturated polar hydroxyl-substituted amide radicals having 1 to 30 carbon atoms; hydroxyl-substituted carbamate radicals having 1 to 30 carbon atoms; ethoxylated amine radicals having 1 to 30 carbon atoms; and guanidine radicals or alkylenylguanidine radicals having 1 to 30 carbon atoms; R 7 in each occurrence independently represents identical or different linear or branched, saturated or unsaturated, divalent hydrocarbon groups having 1 to 20 carbon atoms; a is 2 to 20; b is 10 to 5000; c is 1 to 500; d is 0 to 500; e is >0 to 500; f is 0 to 20; g is 0 to 20; and c is >0.5*e; or their ionic adducts with protic reactants H + A − ; with the proviso that: at least 50% of the R 2 radicals are =R 1 ; and at least one occurrence of R 5 is a guanidine radical or an alkylenylguanidine radical having 1 to 30 carbon atoms.
