Patent ID: 8785587

Claim:
Polyurea-polysiloxane compounds consisting of at least one structural element of the formula (1): wherein ST 1 is chosen from divalent or higher valency, straight-chain, cyclic or branched, saturated, unsaturated or aromatic, substituted or unsubstituted hydrocarbon radicals having up to 1,000 carbon atoms exclusive of the carbon atoms of an optional polyorganosiloxane unit, which can contain one or more groups chosen from —O—, —C(O)—, —NH—, —NR 3 —, and a polydiorganosiloxane unit having 2 to 1,000 silicon atoms, wherein R 3 is a straight-chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radical having up to 40 carbon atoms, which can contain one or more groups chosen from —O—, —C(O)— and —NH—, and R 5 is a straight-chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radical having up to 100 carbon atoms, which can contain one or more groups chosen from —O—, —C(O)— and —NH—, or R 5 is a divalent radical which forms cyclic structures within the radicals ST 1 and/or ST 2 , and ST 2 is a radical of the formula (2) wherein ST 3 is a straight-chain or cyclic or branched, saturated or unsaturated or aromatic, substituted or unsubstituted hydrocarbon radical having 2 to 100 carbon atoms, which can be substituted by —O—, —C(O)—, —NH—, —NR 3 —, wherein R 3 is as defined above, ST 4 is a straight-chain or cyclic or branched, saturated or unsaturated or aromatic, substituted or unsubstituted hydrocarbon radical having 2 to 100 carbon atoms exclusive of the carbon atoms of an optional polyorganosiloxane unit, which can be substituted by —O—, —C(O)—, —NH—, —NR 3 — and by a polydiorganosiloxane unit having 2 to 200 silicon atoms, wherein R 3 is as defined above, and A − is an organic or inorganic anion, with the proviso that at least one of the radicals ST 1 , ST 4 contains a polydiorganosiloxane radical, or acid addition compounds and/or salts of the foregoing.
