Patent ID: 7390479

Claim:
Branched polyorganosiloxane polymer containing at least one group of the structure at least one group of the structure at least one group of the structure as well as at least one branching unit which is selected from the group consisting of S v and V v , where groups V are connected to groups Q and S, groups Q are not connected to groups S the groups S, S v , V, V v , and Q in a polymer molecule can be the same or different and where wherein R 1 can be the same or different and is selected from the group consisting of: C 1 to C 22 alkyl, fluoro(C 1 -C 10 )alkyl and C 6 -C 10 aryl, and n=0 to 1000, S v is a three or higher valent organopolysiloxane unit, Q is a divalent organic group containing at least one ammonium group, V represents a divalent, straight-chain, cyclic or branched, saturated, unsaturated, or aromatic hydrocarbon group with up to 1,000 carbon atoms which optionally contains one or more groups selected from the group consisting of —O—, —NH—, —NR 1 —, wherein R 1 is defined as above, —C(O)—, -and —C(S)—, and which, optionally, is substituted with one or more hydroxyl groups, V v represents a trivalent or higher valent, straight-chain, cyclic or branched, saturated, unsaturated, or aromatic hydrocarbon group with up to 1000 carbon atoms which optionally contains one or more groups selected from the group consisting of —O—, —NH—, —NR 1 —, wherein R 1 is defined as above, —C(O)—, and —C(S)—, and which, optionally, is substituted with one or more hydroxyl groups, and wherein the positive charges resulting from the ammonium group are neutralized by organic or inorganic acid anions and their acid addition salts.
